[Industrial Field of Application] The present invention relates to a heat resistance modifier for synthetic resins. More specifically, for synthetic resin molded products, antistatic effect, dropless effect, surface lubrication effect, color tone improvement effect based on improved coloring material dispersion, or lubricity effect necessary during molding, mold release effect, crystallization. The present invention relates to a heat resistance modifier for synthetic resins that exhibits a heat-resistance modifier effect. [Prior Art and Problems] Conventionally, modifiers have been used in synthetic resin products for various purposes depending on the type of resin. The purposes can be broadly classified as follows. To improve moldability...lubricants, mold release agents,
Crystallization accelerator To improve product properties... antistatic agent,
Drop-free agents, surface lubrication improvers, color tone improvers The modifiers conventionally used for the above purposes have sufficient heat resistance (meaning product coloring or fuming due to volatilization of active ingredients) during processing. There were problems in that the effects were not satisfactory or the effects themselves were not satisfactory. [Means for Solving the Problems] As a result of intensive studies to eliminate these drawbacks, the present inventors have discovered that when a specific compound is added to a synthetic resin, it is extremely effective for the above purposes. The present inventors have found that they are not only effective, but also have excellent heat resistance during processing, leading to the completion of the present invention. That is, the present invention is based on the general formula () In the formula, A is an alkyl group having 1 to 22 carbon atoms or an alkyl group having 2 to 22 carbon atoms.
22 acyl group ● R 1 is ethylene or propylene, or a mixed alkylene group containing two or more of these ● m is an integer of 1≦m≦30 ● n is a compound represented by an integer of 1≦n≦4 The present invention provides a heat resistance modifier for synthetic resins. [Function] Specific examples of the compound of formula () according to the present invention are as follows. (Hereinafter, abbreviated as the compound of the present invention) (Hereinafter, abbreviated as the compound of the present invention) (Hereinafter, abbreviated as the compound of the present invention) (Hereinafter, abbreviated as the compound of the present invention) (Hereinafter, abbreviated as the compound of the present invention) In the compound of formula () according to the present invention, the number of carbon atoms of A and the number of added moles of alkylene oxide m
can be arbitrarily selected within the above range.
That is, A is a so-called hydrophobic group, and the smaller the number of carbon atoms, the more hydrophilicity increases, and conversely, the larger the number of carbon atoms, the more lipophilicity is improved. On the other hand, alkylene oxide is generally hydrophilic, and has the property of improving hydrophilicity as m increases. Therefore, A
By arbitrarily adjusting the number of carbon atoms and m, hydrophilicity and hydrophobicity can be appropriately balanced.
This is very important for modifiers for synthetic resins; for example, polyamide resins and polyacrylonitrile, which have relatively high hydrophilicity (high cohesive energy density), have relatively high hydrophilic properties. Modifiers are suitable. Furthermore, for materials having intermediate hydrophilic-lipophilic properties such as polyethylene terephthalate, polybutylene terephthalate, and polyalkyl acrylate resins, a modifier having slightly less hydrophilicity than the above-mentioned modifier is preferable. Furthermore, for hydrophobic resins such as polyolefins and halogenated vinyl resins, modifiers with even lower hydrophilicity are suitable. In this way, the modifier of general formula () is
From hydrophobic resin (low energy density resin) to hydrophilic resin (high energy density resin), A and m
It has the advantage that a wide range of choices can be made by appropriately adjusting. Generally, in the processing of the above-mentioned resins, a modifier is usually added to the molten resin, and the modifier is exposed to high temperatures of 150°C to 300°C. For this reason, the modifier often evaporates or decomposes, emitting smoke, and impairing the hue of the product due to coloring. The modifier of formula () according to the present invention has excellent heat resistance, and hardly generates smoke or discolors when heated. In order for the synthetic resin modifier according to the present invention to exhibit its intended performance, it is necessary to use 100 parts of resin (by weight,
(the same applies hereinafter), it is necessary to add 0.1 to 5.0 parts, preferably 0.2 to 3.0 parts. If it is less than 0.1 part, the effect will be reduced to such an extent that it can hardly be expected.
If it exceeds 5 parts, the physical properties of the resin will be adversely affected. The modifier for synthetic resins according to the present invention may be added to synthetic resins at the time of resin production or at an appropriate step after production, or it may be mixed and added to resin pellets or resin compounds after resin processing. Also good. In any case, it provides a satisfactory effect during molding and imparts excellent performance to the molded product after molding. Further, the effect is exhibited regardless of the shape of the molded product, and the object of the present invention is achieved. The method for molding the resin to which the synthetic resin modifier of the present invention is added can be the same as the method for molding the resin without the addition. That is, the resin can be molded by injection molding, extrusion molding, blow molding, calendar molding, etc. under the optimum processing conditions for the resin. Plasticity-resistant synthetic resins can generally be used as the target synthetic resin for the heat resistance modifier for synthetic resins according to the present invention, but polyolefin resins such as polyethylene, polypropylene, polybutylene, and polyisobutylene, as well as polyolefin resins such as these Copolymers with polymerizable vinyl monomers such as vinyl acetate, vinyl propionate, vinyl benzoate, acrylic acid, methacrylic acid, acrylic esters, methacrylic esters, or polystyrene, AS,
Styrenic resins such as ABS, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyamide resins, polyhalogenated vinyl resins such as polyvinyl chloride resin, polyacrylonitrile, polyvinyl carboxylate,
Polyacetal, etc. [Effects of the Invention] The heat resistance modifier for synthetic resins according to the present invention is effective for the above synthetic resins, but antistatic agents include polyolefin resins, styrene resins, polyester resins, polyvinyl chloride resins, and non-droplet resins. Agents include polyolefin resin, copolymerized polyolefin resin,
Particularly effective for soft polyvinyl chloride resin. In addition, as surface lubrication improvers, polyacetal,
Effective for polybutylene terephthalate, etc.
It is effective as a color tone improver (color material dispersant) for all resins. Furthermore, it is effective as a lubricant and mold release agent for processing styrene resins and polyvinyl chloride.
As a crystallization promoter, it is particularly effective in processing polyethylene terephthalate. [Example] The present invention will be specifically described below with reference to Examples. Example 1 Low density polyethylene resin (Sumikasen F223-
The compounds shown in Table 1 were added to 1), and a film was produced at 200° C. using an extruder in a conventional manner. Table 1 below summarizes the film's antistatic property (surface resistance), drop-free property, and heat resistance (smoke generation, film coloring).
