Problems solved by technology

However, since polyphenylene ether is an amorphous resin, its resistance to fats and oils and organic solvents is not sufficient, and there are problems in its use and environment being limited to some extent.
[0003] Therefore, in some applications, attempts have been made to improve chemical resistance by alloying PPE resins with crystalline resins, but the impact resistance deteriorates sharply in the temperature range below the glass transition temperature of the crystalline resins. question

preparation example Construction

[0261] The preparation method of the component (d) is not particularly limited, and a catalyst (for example, a catalyst based on titanium, metallocene, or vanadium, for example, a catalyst based on titanium, metallocene, or vanadium) that can easily obtain a high molecular weight α-olefin polymer under normal processing conditions can be used. etc.) method etc. Among these, the method of using a metallocene catalyst and a titanium chloride catalyst is preferable from the viewpoint of the stability of structure control. As a method for producing the ethylene-α-olefin copolymer, known methods described in Japanese Patent Application Laid-Open No. 6-306121, Japanese Patent Application Laid-Open No. 7-500622, and the like can be used.

Description

technical field [0001] The present invention relates to a resin composition, a method for producing the resin composition, and a molded body. Background technique [0002] Polyphenylene ether (hereinafter sometimes simply referred to as "PPE") has advantages such as heat resistance, low specific gravity, and flame retardancy, and is used in various applications including OA and automotive applications. However, since polyphenylene ether is an amorphous resin, its resistance to oils and fats and organic solvents is insufficient, and there is a problem that the usage and the environment are limited to some extent. [0003] Therefore, in some applications, an attempt has been made to improve chemical resistance by alloying PPE resin with a crystalline resin, but the impact resistance rapidly deteriorates in a temperature range below the glass transition temperature of the crystalline resin. question. [0004] On the other hand, the addition of a thermoplastic elastomer having...
