Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a polyphenylene ether resin composition with excellent blow moldability and a molded article produced from the same.

(Prior art) Polyphenylene ether has a glass transition temperature of 210-2
It has a high heat resistance of 20° C., and once melted, it becomes inferior, so it is characterized by good dimensional accuracy. However, due to poor moldability and chemical resistance,
It is not suitable for the production of injection molded products or blow molded products.

On the other hand, polyamide has a high melting point and high glass transition temperature, low melt viscosity, and good chemical resistance, so it is widely used in injection molding. However, since polyamide has a low melt tension, parison drawdown is severe during blow molding, and it is difficult to obtain a large hollow product by itself. Currently, it is used in multilayer extrusion with high-density polyethylene, which has a slightly high melt tension, to impart gas barrier properties to products.

In recent years, many attempts have been made to obtain polymer alloys that have both the characteristics of polyphenylene ether and those of polyamide. For example, JP-A-56-47432
No., JP-A-56-49753, JP-A-57-3615
As described in each publication No. 0, etc., polymer alloys for injection molding have been provided which have improved mechanical properties, heat resistance, and chemical resistance. However, it has been found that even if these are used for blow molding purposes, the drawdown is large as described above, resulting in a product with a large thickness deviation, making it impractical.

(Problems to be Solved by the Invention) The present invention has the same good quality as these polymer alloys in terms of mechanical properties, heat resistance, and chemical resistance, while significantly improving parison drawdown characteristics in blow molding. The purpose is to improve. As a result, it can be effectively used for parts of automobile exterior panels, fuel tanks, oil tanks, radiators, duct hoses, harness tubes, air spoilers, bumpers, side protectors, seats, housings such as Noah shelves, and chemical bottles. The purpose of the present invention is to provide a polyphenylene ether resin composition.

(Means for Solving the Problems) The present invention consists of the following components, and has a melt flow rate (M
FR) is 0, 01-5 dg/min, melt tension fM
This is a polyphenylene ether resin composition having Tl of 4 g or more.

(A) Intrinsic viscosity [η
] is in the range of 0.35 to 0.75 dl/g polyphenylene ether CB) relative viscosity nr (JIS K6810.98%
(measured in sulfuric acid) is 2.5 or more (C) impact modifier (D) compatibilizer and (E) ethylenically unsaturated silane compound-modified polyolefin polymer (constituent components) (A) polyphenylene Ether The polyphenylene ether used in the present invention has a repeating structural unit represented by -Noshiro: In the formula, Q is each independently hydrogen, halogen, a hydrocarbon group having no tertiary α-carbon atom, halogen one selected from the group consisting of a halohydrocarbon group in which atoms are substituted via at least 2 carbon atoms, a hydrocarbonoxy group and a halohydrocarbonoxy group in which halogen atoms are substituted via at least 62 carbon atoms; represents a valence substituent, and each Q may be the same or different from each other.

Copolymers such as copolymers with dolimethylphenol can also be mentioned.

Furthermore, the polyphenylene ether used in the present invention includes modified polyphenylene ethers such as those grafted with styrene monomers (eg, styrene, p-methylstyrene, α-methylstyrene, etc.).

The method for producing polyphenylene ether corresponding to the above is as follows:
For example, US Pat. No. 3,306,874, No. 3
No. 306875, No. 3257357 and No. 32573
No. 58 and Japanese Patent Publication No. 52-17880 and Japanese Patent Application Laid-Open No. 50-51197.

The polyphenylene ether used in the present invention is 30%
Intrinsic viscosity [η] measured in chloroform at ℃ is 0.3
It is preferable that the intrinsic viscosity is in the range of 5 to 0.75 dl/g.If the intrinsic viscosity is less than 0.35 dl/g, the impact strength of the composition will be poor and it is not preferable.
If it exceeds g, it is not preferable because the gel content is large and the appearance of the molded product deteriorates.

(B) Polyamide The polyamide used in the present invention is hexamethylene diamine, decamethylene diamine, dodecamethylene diamine, 2.2.4- or 2.4.4-trimethylhexamethylene diamine, 1.3- or , 1.4-bis(aminomethyl)cyclohexane, bis(p-aminocyclohexylmethane), aliphatic, alicyclic, aromatic diamines such as m- or p-xylylene diamine, adipic acid, superric acid, Polyamides obtained by polycondensation with aliphatic, alicyclic, aromatic dicarboxylic acids such as sebacic acid, cyclohexanedicarboxylic acid, terephthalic acid, and isophthalic acid; aminocarboxylic acids such as ε-aminocaproic acid and 11-aminoundecanoic acid.

(measured in 8% sulfuric acid) is 2.5 or more. If it is 2.5 or less, the melt flow rate (MF
If the RI exceeds 5 dg/min, the moldability decreases, which is undesirable.If the relative viscosity exceeds 4.0, the drawdown of the molten parison will be small, and medium to large products with a parison length exceeding 1 m may also be used. It is preferred because it can be stably molded.
