Problems to be solved by the invention
However, gears generally have a function of transmitting rotational power through engagement of gears with each other.

Therefore, the performance required for the gear includes not only friction/wear resistance but also durability against fatigue.
Although the POM resin composition described in patent document 1 is excellent in sliding characteristics, there is still room for further improvement as a material for a resin gear.

A kind of electronic device
In the method for producing a polyacetal resin composition according to the present embodiment, a polyacetal resin composition having excellent sliding properties, particularly excellent abrasion resistance, and excellent fatigue durability when applied to gears can be obtained by containing a predetermined amount of the components (B) to (F) in 100 parts by mass of the polyacetal copolymer (a). It is known from patent document 1 that the excellent sliding properties are mainly attributable to the components (B) to (F). On the other hand, it is found that the fatigue durability is excellent when the polyacetal copolymer is applied to gears, and the polyacetal copolymer (A) obtained by a predetermined production method cannot be obtained by adding only the components (B) to (F). However, since the structure and properties of the polyacetal copolymer (A) are difficult to specify, it is not clear how the polyacetal copolymer (A) contributes. It is known that the sliding properties and fatigue durability in the case of application to gears are improved by interaction of the polyacetal copolymer (A) obtained by the predetermined production method with the components (B) to (F).
The following first describes each component used in the production method of the present embodiment.
[ (A) polyacetal copolymer ]
In this embodiment, (a) the polyacetal copolymer is obtained by adding an alkaline inactivating agent (d) to a reaction product obtained by copolymerizing a heteropoly acid represented by the following general formula (1) with a polymerization catalyst (c) using a cyclic ether and/or cyclic methylal having at least 1 carbon-carbon bond as a comonomer (b) and then performing melt kneading treatment to inactivate the polymerization catalyst (c), wherein the main monomer (a) is 80 to 99.9 mol% of the total monomer which is trioxane.
(Main monomer (a))
As the main monomer (a), trioxane may be used. Trioxane is a cyclic trimer of formaldehyde, and is generally obtained by reacting an aqueous formaldehyde solution in the presence of an acidic catalyst, and is purified by a method such as distillation. The trioxane used for polymerization is preferably one in which impurities such as water and methanol are reduced as much as possible.
(comonomer (b))
As comonomer (b) cyclic ethers and/or cyclic formals having at least 1 carbon-carbon bond can be used. Representative examples of the compound used as the comonomer (b) include 1, 3-dioxolane, diethylene glycol methylal, 1, 4-butanediol methylal, 1, 3-dioxane, ethylene oxide, propylene oxide, epichlorohydrin, and the like. Among them, 1, 3-dioxolane, diethylene glycol methylal, 1, 4-butanediol methylal, 1, 3-dioxane and ethylene oxide are preferable from the viewpoint of polymerization stability.
In addition, a known modifier comonomer such as a branching agent may be added as the third comonomer component in addition to the main monomer (a) and the comonomer (b) within a range that does not significantly deteriorate the performance of the polyacetal resin composition obtained.
In this embodiment, the amount of the compound selected from the cyclic ether and/or cyclic methylal used as the comonomer (b) is preferably 0.1 to 20 mol%, more preferably 0.2 to 10 mol% based on the total monomer (total amount of the main monomer and the comonomer). When the amount of the comonomer (b) is less than 0.1 mol%, the unstable terminal part of the crude polyacetal copolymer produced by polymerization may be increased, and the stability may be deteriorated.
When the amount of the comonomer exceeds 20 mol%, the resulting copolymer may become soft, resulting in a decrease in melting point.
(polymerization catalyst (c))
In the present embodiment, in the production of the polyacetal copolymer as described above, a heteropoly acid represented by the following general formula (1) is used as the polymerization catalyst (c).
H m [M 1 x ·M 2 y O Z ]·nH 2 O.cndot.general formula (1)
In the formula (1), M 1 Represents a central element composed of 1 or 2 elements selected from P and Si. M is M 2 Represents 1 or more coordinating elements selected from W, mo and V. x is an integer of 1 to 10, y is an integer of 6 to 40, z is an integer of 10 to 100, m is an integer of 1 to 1, and n is an integer of 0 to 50.
Specific examples of the heteropoly acid include phosphomolybdic acid, phosphotungstic acid, phosphomolybdic vanadic acid, phosphotungstic vanadic acid, tungstic silicic acid, silicomolybdic tungstic acid, silicomolybdic vanadic acid, and the like. Among them, from the viewpoints of polymerization stability and stability of the heteropoly acid itself, the heteropoly acid is preferably 1 or more of silicomolybdic acid, tungstic silicic acid, phosphomolybdic acid and phosphotungstic acid.
In the present embodiment, the amount of the heteropoly-acid to be used varies depending on the kind thereof, and the polymerization reaction can be appropriately modified, but is generally in the range of 0.05 to 100ppm (hereinafter, mass/mass ppm) and preferably 0.1 to 50ppm based on the total amount of the monomers to be polymerized. In addition, as the phosphomolybdic acid, phosphotungstic acid and other very strong heteropoly acid, 0.1-10 ppm of the use amount is sufficient.
Even if the catalyst is used in a small amount, the catalyst can be used to inhibit unstable formate end groups (-O-CH=O) and hemiacetal end groups (-O-CH) by keeping the unfavorable reactions such as main chain decomposition and depolymerization of the polymer to a minimum 2 -OH), etc., and is economically advantageous.
In order to uniformly perform the reaction, the polymerization catalyst is preferably diluted with an inert solvent which does not adversely affect the polymerization, and added to the main monomer (a) and/or the comonomer (b) to be used. The inert solvent is preferably an ester obtained by condensing a low-molecular-weight carboxylic acid having 1 to 10 carbon atoms such as formic acid, acetic acid, propionic acid, butyric acid, etc., with a low-molecular-weight alcohol having 1 to 10 carbon atoms such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-methyl-1-propanol, 2-methyl-2-propanol, 1-pentanol, 3-methyl-1-butanol, 1-hexanol, etc.; ketones having a low molecular weight of 1 to 10 such as acetone, 2-butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone, methyl isobutyl ketone, methyl tert-butyl ketone, and the like, but are not limited thereto. Methyl formate, ethyl formate, methyl acetate, ethyl acetate, butyl acetate, acetone, 2-butanone, methyl isobutyl ketone, and the like are most suitable when industrial availability and the like are also considered. The polymerization catalyst is suitably dissolved in the above-mentioned inert solvent at a concentration of 1 to 30 mass/mass%, but is not limited thereto. In addition, a method of adding a predetermined amount of the polymerization catalyst to the polymerization system and polymerizing the mixture in advance in a part or the whole of any 1 or more of the main monomer (a), the comonomer (b), the molecular weight regulator, and the like is also preferable.
[ preparation of copolymer ]
In the present embodiment, the production of the crude polyacetal copolymer by the polymerization can be conventionally carried out by the same equipment and method as those for the copolymerization of trioxane. That is, the batch type, continuous type, and semi-continuous type are all possible, and a method of obtaining a solid powder bulk polymer with the progress of polymerization using a liquid monomer is generally used. As the polymerization apparatus used in the present embodiment, a reaction tank with a stirrer which is generally used in a batch type may be used. Further, as the continuous type, a kneading extruder, a biaxial screw type continuous extrusion mixer, a biaxial paddle type continuous mixer, and other continuous polymerization apparatuses of trioxane and the like proposed so far can be used. Furthermore, 2 or more types of polymerizers may be used in combination.
The polymerization method is not particularly limited, but as previously proposed, the comonomer (b) and the heteropoly acid as the polymerization catalyst (c) may be sufficiently mixed while maintaining a liquid phase state in advance, and the obtained mixed liquid may be supplied to a polymerization apparatus together with trioxane as the main monomer (a) to perform copolymerization. Thus, the amount of the catalyst necessary can be reduced, and as a result, a polyacetal copolymer having a smaller formaldehyde emission amount can be advantageously obtained, which is a more suitable polymerization method. The polymerization temperature is carried out in the temperature range of 60 to 120 ℃.
In this embodiment, when the main monomer (a) and the comonomer (b) are polymerized to prepare the polyacetal copolymer, a known chain transfer agent, for example, a linear acetal having a low molecular weight such as formaldehyde dimethyl acetal (methyl) may be added to adjust the degree of polymerization.
Further, the polymerization reaction is desirably carried out in a state where impurities having active hydrogen, such as water, methanol, formic acid, and the like, are substantially absent, for example, in a state where they are each 10ppm or less. For this reason, it is desirable to use trioxane, cyclic ether and/or cyclic methylal prepared so as to be as free of these impurity components as possible as a main monomer and a comonomer.
Next, deactivation of the polymerization catalyst by adding an alkaline deactivator will be described.
(alkaline deactivator (d))
The type and method of adding the alkaline deactivator are not particularly limited, but it is preferable that the alkaline deactivator is added to the crude polyacetal copolymer in its original state without washing the crude polyacetal copolymer, and the mixture is melt-kneaded, so that the alkaline deactivator can be used for deactivation of the polymerization catalyst and stabilization of the unstable terminal of the crude polyacetal copolymer. Specifically, the alkali inactivating agent preferably contains at least 1 selected from carbonates, bicarbonates, or carboxylates of alkali metal elements or alkaline earth metal elements or hydrates thereof, and triazine ring-containing compounds having an amino group or a substituted amino group.
In the case of using a carbonate, bicarbonate, or carboxylate of an alkali metal element or an alkaline earth metal element or a hydrate thereof, the formaldehyde generation amount of the composition to be finally obtained is particularly low, and more preferably. Specifically, it is more preferable to contain at least 1 selected from sodium formate, sodium acetate, sodium carbonate, sodium bicarbonate, disodium succinate, sodium laurate, sodium palmitate, sodium stearate, and calcium stearate.
In this embodiment, the above-mentioned alkali deactivator may be used in 1 kind, or in combination of plural kinds, or in the form of a hydrate, a mixture, a double salt, or the like.
After the polymerization and deactivation treatment, the unreacted monomers may be separated, recovered, dried, and the like by a conventionally known method, if necessary.
Next, the components (B) to (F) used in the present embodiment will be described below.
[ (B) modified olefin Polymer obtained by modifying olefin Polymer with at least 1 selected from unsaturated carboxylic acids, anhydrides of unsaturated fatty acids and derivatives thereof ]
In the present specification, the modified olefin polymer is also referred to as a "(component B"). The polyacetal resin composition according to the present embodiment is excellent in sliding characteristics by containing the component (B). In contrast, when an olefin polymer other than the component (B) is contained in the polyacetal resin composition, the sliding properties are poor.
The olefin-based polymer (before modification) used in the component (B) includes a single polymer of an α -olefin such as ethylene, propylene, butene, hexene, octene, nonene, decene, dodecene, etc., a random, block or graft copolymer composed of 2 or more of them, a non-conjugated diene component such as 1, 4-hexadiene, dicyclopentadiene, 5-ethylidene-2-norbornene, 2, 5-norbornadiene, etc., a conjugated diene component such as butadiene, isoprene, piperylene, etc., an α, β -unsaturated acid such as acrylic acid, methacrylic acid, etc., a derivative of an α, β -unsaturated acid such as an ester thereof, etc., acrylonitrile, styrene, an aromatic vinyl compound such as α -methylstyrene, etc., a vinyl ester such as vinyl acetate, a vinyl ether such as an ethylene methyl ether, etc., and a random, block or graft copolymer composed of at least 1 of a comonomer component such as a derivative of an ethylene compound, etc., regardless of the degree of polymerization, side chain, branching, degree, copolymerization, and the like.
Examples of the olefin-based polymer include high-pressure polyethylene, medium-low-pressure polyethylene, gas-phase ethylene- α -olefin copolymer, LLDPE, polypropylene, polybutene, ethylene-vinyl acetate copolymer, ethylene-methyl acrylate copolymer, ethylene-ethyl acrylate copolymer, ethylene-butyl acrylate copolymer, ethylene-propylene copolymer, and ethylene-propylene-diene terpolymer. Preferably, polyethylene, ethylene-methyl acrylate copolymer, ethylene-ethyl acrylate copolymer.
The component (B) used in the present embodiment is a modified olefin polymer obtained by modifying at least 1 selected from unsaturated carboxylic acids such as acrylic acid, methacrylic acid, maleic acid, citraconic acid, itaconic acid, tetrahydrophthalic acid, norbornene diacid, methylnorbornene diacid, allylsuccinic acid, and unsaturated carboxylic acid anhydrides such as maleic anhydride, citraconic anhydride, itaconic anhydride, tetrahydrophthalic anhydride, norbornene dianhydride, methylnorbornene dianhydride, allylanhydrous succinic acid, derivatives thereof, and the like.
As the preferable component (B), the Melt Flow Rate (MFR) is 0.01 to 100g/10 min, more preferably 0.1 to 50g/10 min, and particularly preferably 0.2 to 30g/10 min. Furthermore, the Melt Flow Rate (MFR) is determined according to ISO 1133.
Specific examples of the preferable component (B) include polyethylene modified with maleic anhydride, polypropylene, ethylene-propylene copolymer, ethylene-ethyl acrylate copolymer, and the like. Among them, when the component (B) contains a polyethylene modified with maleic anhydride, it is preferable in that the sliding properties of a molded article obtained by molding the polyacetal resin composition are improved.
As a modification method thereof, a method of heating and reacting an olefin polymer and at least 1 compound selected from the group consisting of an unsaturated carboxylic acid, an anhydrous compound thereof, and a derivative thereof in a solution state or a molten state in the presence of a radical initiator such as an appropriate organic peroxide or the like is suitable, but not particularly limited thereto. The mixing amount of the two components is preferably 0.1 to 20 parts by mass, more preferably 0.1 to 10 parts by mass, based on 100 parts by mass of the olefin polymer. When the amount of the effective compound in the olefin polymer modified with such a compound is too small, the affinity between the component (a) and the component (B) may be insufficient, and when the amount is too large, physical properties such as sliding properties may be lowered to be improved.
In the present embodiment, the component (B) is preferably contained in an amount of 0.5 to 10 parts by mass, more preferably 2 to 7 parts by mass, based on 100 parts by mass of the component (a). In the polyacetal resin composition obtained, the blending amount of the component (B) is less than 0.5 part by mass, and the frictional wear may be increased, which is not preferable. (B) If the mixing amount of the components exceeds 10 parts by mass, there is a possibility that the mechanical properties may be lowered, and thus it is not preferable.
[ (C) alkylene glycol-based Polymer having Primary or Secondary amino groups and having a number average molecular weight of 400 to 500,000 ]
In the present specification, the alkylene glycol polymer is also referred to as a "(C) component". The polyacetal resin composition according to the embodiment is excellent in sliding characteristics by containing the component (C).
The alkylene glycol polymer having a primary or secondary amino group as the component (C) is a homopolymer or copolymer of ethylene glycol, propylene glycol or tetramethylene glycol, and has a primary or secondary amino group at the terminal or in the molecular chain thereof. Further, a polymer slightly modified with an ester with a fatty acid, an ether with an aliphatic alcohol, or the like may be formed. Examples thereof include polyethylene glycol, polypropylene glycol, polytetramethylene glycol, and copolymers of these constituent units, and those having at least 1 aminopropyl group and aminooctyl group.
The kind of the polymer is not particularly limited, but it is preferable in that the sliding property of a molded article obtained by molding the polyacetal resin composition is improved if the alkylene glycol-based polymer is a polymer slightly modified with an ester of a fatty acid, an ether of an aliphatic alcohol or the like.
(C) The number average molecular weight of the component (A) is 400 to 500,000, preferably 400 to 100,000, more preferably 1,000 to 6,000. This is because, by mixing the component (C), dispersibility of the component (B) in the polyacetal resin is improved, but the component (C) has a number average molecular weight of less than 400, and mechanical physical properties and sliding properties of the polymer material as the component (a) or the component (B) are impaired, and the number average molecular weight exceeds 50 ten thousand, and the melt viscosity is increased, so that the dispersion in the polyacetal resin becomes difficult.
(C) The mixing amount of the component (a) is 0.01 to 5 parts by mass, more preferably 0.1 to 4 parts by mass, still more preferably 0.3 to 3 parts by mass, and particularly preferably 1 to 2 parts by mass, based on the component (a).
Of these, the blending amount of the component (C) is preferably 1 part by mass or more, in that the sliding properties of a molded article obtained by molding the polyacetal resin composition can be significantly improved. (C) When the content is less than 0.01 parts by mass, the effect of modifying the sliding properties of the molded article cannot be sufficiently obtained, and when it exceeds 5 parts by mass, the mechanical properties are deteriorated, which is not preferable.
[ (D) BET specific surface area of 15m 2 Per gram or less, an average particle diameter of 50nm to 200nm, and surface-untreated, cubic calcium carbonate]
In this specification, this calcium carbonate is also referred to as the "(D) component. The polyacetal resin composition according to the embodiment is excellent in sliding characteristics by containing the component (D).
Conventionally, in order to improve the sliding properties of resin molded articles, it has been known to use an inorganic filler as a component of a polyacetal resin composition. As the inorganic filler, calcium carbonate, potassium titanate, barium carbonate, talc, wollastonite, mica, zinc oxide, and the like are known. However, in the present embodiment, calcium carbonate is an essential component. The inorganic filler is not preferable because the surface properties of the molded article are not so excellent as compared with the case of containing the component (D), even if the inorganic filler other than calcium carbonate is contained as the component (D).
(D) The BET specific surface area of the component is 15m 2 And/g or less. In the present specification, BET specific surface area means a specific surface area (surface area per unit mass) obtained from the adsorption amount at the completion of a monolayer obtained by the BET formula using nitrogen as a reference gas, and the BET specific surface area measurement method is as defined in ASTM D-3037And (5) setting. When the BET specific surface area exceeds 15m 2 In the case of/g, the molded article obtained by molding the polyacetal resin composition is not preferable because of poor surface properties and sliding properties.
(D) The average particle diameter of the component (A) is 50nm to 200nm, more preferably 80nm to 170 nm. In the present specification, the particle diameter means an arithmetic average value of the long diameter and the short diameter when the long diameter and the short diameter of the target particle are measured by observation at 30,000 times magnification using a scanning electron microscope S3000H manufactured by hitachi High-Tech company. In the present specification, the average particle diameter means an arithmetic average of particle diameters of 100 samples. When the average particle diameter is less than 50nm, there is a possibility that the condensation is carried out 2 times in the product, and when the average particle diameter exceeds 200nm, it is not preferable in that the surface properties and sliding properties of a molded article obtained by molding the polyacetal resin composition are poor.
(D) The components are surface untreated. When the surface of component (D) is treated, the molded article obtained by molding the polyacetal resin composition is not preferable because of poor abrasion property.
In the present specification, "surface-untreated" means that the surface of the calcium carbonate particles is not treated with a surface treatment agent such as an epoxy compound, an isocyanate compound, a titanate compound, or a silane compound.
(D) The components are cubic. Here, the cube shape includes not only a cube that is a regular hexahedron, but also a hexahedron that cannot be said to be a complete cube but also a nearly cubic shape.
(D) When the shape of the component is not a cube but is an irregular shape, it is not preferable in that the surface properties and sliding properties of a molded article obtained by molding the polyacetal resin composition are poor. In the present specification, whether or not the component (D) is cubic in shape is confirmed by, for example, burning the product at 500 ℃ for 3 hours and observing the residue with an electron microscope.
(D) The mixing amount of the component (a) is 0.1 to 20 parts by mass, more preferably 0.1 to 1 part by mass. (D) If the content is less than 0.1 parts by mass, the frictional wear amount may be increased, and if it exceeds 20 parts by mass, the surface properties may be deteriorated, which is not preferable.
[ (E) partial esters of polyhydric alcohols having 2 to 4 members ]
In this specification, the partial esters of the polyols are also referred to as the "(E) component. The polyacetal resin composition according to the present embodiment contains the component (E), and thus is excellent in surface properties and sliding properties.
Conventionally, as a component of a polyacetal resin composition, use of a lubricant has been known. Further, as lubricants, mineral oils, hydrocarbons, fatty acids, aliphatic alcohols, aliphatic esters formed from fatty acids and aliphatic alcohols, partial and/or full esters of polyhydric alcohols, esters of carboxylic acids and inorganic acids, amides of fatty acids and amine compounds, metal soaps, natural waxes, silicones and derivatives thereof, substituted diphenyl ethers, and the like are known.
However, in the present embodiment, both the partial ester as the component (E) and the α -olefin oligomer as the component (F) described later are essential components.
Even if the lubricant contains other lubricants than the component (E) and the component (F), it cannot be said that the surface properties are excellent as in the present embodiment, and therefore, it is not preferable.
Specific examples of the component (E) include glycerol monostearate, glycerol distearate, glycerol monobehenate, pentaerythritol monostearate, and the like.
The partial ester as the component (E) is not preferable in that the surface properties and sliding properties of a molded article obtained by molding the polyacetal resin composition are poor if the ester is not a partial ester.
(E) The mixing amount of the component (a) is 0.1 to 10 parts by mass, more preferably 0.5 to 2 parts by mass. (E) If the content is less than 0.1 parts by mass, the frictional wear may increase, and if it exceeds 10 parts by mass, leakage may occur, which is not preferable.
[ (F) alpha-olefin oligomer ]
In this specification, the oligomer is also referred to as the "(F) component". The polyacetal resin composition according to the present embodiment is excellent in sliding characteristics by containing the component (F).
(F) The mixing amount of the component (a) is 0.1 to 10 parts by mass, more preferably 1 to 5 parts by mass. (F) If the content is less than 0.1 parts by mass, the sliding properties of a molded article obtained by molding the polyacetal resin composition may be poor, and if it exceeds 10 parts by mass, leakage or peeling may occur, which is not preferable.
[ other stabilizers and additives ]
The polyacetal resin composition according to the present embodiment may further comprise various known stabilizers to enhance stability. Further, various known additives may be further mixed in accordance with the intended use to improve physical properties thereof.
Examples of the additives include various colorants, mold release agents, nucleating agents, antistatic agents, other surfactants, and heterogeneous polymers (other than the aforementioned graft copolymers). Further, 1 or 2 kinds of fibrous, granular or plate-like fillers such as inorganic, organic, or metal may be mixed and used as long as the properties of the target composition of the present embodiment are not significantly reduced.

Preparation of polyacetal copolymer (A)
[ polyacetal copolymers A-1 to A-4 ]
As the polymerization apparatus, a continuous biaxial polymerization machine was used. The polymerizer has a housing for passing a medium for heating or cooling on the outside, and 2 rotary shafts each having a plurality of impellers for stirring and propulsion are provided in the longitudinal direction inside the housing. In the housing of the biaxial polymerization machine, a mixed solution of trioxane as the main monomer (a), 1, 3-dioxolane (3.3 mass% to total monomer) as the comonomer (b), and 1500 mass ppm (to total monomer) of formaldehyde dimethyl acetal as the chain transfer agent was continuously supplied to one end of the housing while rotating 2 rotating shafts at a constant speed by a heating medium of 80 ℃. Then, as a polymerization catalyst (methyl formate solution) shown in table 1, the above mixed solution was continuously added in an amount shown in table 1 with respect to the total monomers to carry out copolymerization. In Table 1, the amount of the polymerization catalyst added was the mass ratio (unit: ppm) to the total of the total monomers. Then, the crude polyacetal copolymer was discharged from a discharge port provided at the other end of the polymerizer, and an alkaline deactivator as shown in Table 1 was added for deactivating the polymerization catalyst. In Table 1, the amount of the alkaline deactivator was defined as the mass ratio (unit: ppm) to the crude polyacetal copolymer. Next, 0.3 parts by mass of triethylene glycol-bis [ 3- (3-t-butyl-5-methyl-4-hydroxyphenyl) propionate ] was added as an antioxidant, and the mixture was melt kneaded and extruded at a temperature of 220℃and a vacuum degree of a vent portion of 5mmHg using a twin-screw extruder having a vent. The polyacetal copolymers (A-1 to A-4) were obtained by the above-mentioned steps. Further, the Melt Flow Rate (MFR) of each polyacetal copolymer was measured using a measuring device: melt index L202 (manufactured by TAKARA thermistor) under a load of 2.16kg at 190℃in accordance with ISO 1133.
[ polyacetal copolymer A' -1 ]
As the catalyst, boron trifluoride in a gaseous state was used, and the process was carried out in the same manner as in the polyacetal copolymers A-1 to A-4 until the crude polyacetal copolymer was discharged from the discharge port provided at the other end of the polymerizer. The discharged reaction product was rapidly passed through a crusher and added to a 60℃aqueous solution containing 0.05 mass% of triethylamine to deactivate the catalyst. Then, the crude polyacetal copolymer was obtained by separation, washing and drying. Subsequently, 3 mass% of a 5 mass% aqueous solution of triethylamine and 0.3 mass% of pentaerythritol-tetrakis [ 3- (3, 5-di-t-butyl-4-hydroxyphenyl) propionate ] were added to 100 parts by mass of the crude polyacetal copolymer, and the mixture was melt-kneaded at 210℃by a biaxial extruder to remove an unstable part, thereby obtaining a polyacetal copolymer of the polyacetal copolymer A' -1.
