【発明の詳細な説明】 本発明は、耐溶剤クラツク性を改善されたポリフエニレ
ンエーテル系樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polyphenylene ether resin composition having improved solvent crack resistance.

が、米国特許第3,383,435号明細書より知られている。Polyphenylene ether resin is useful as a resin for molding materials because of its excellent mechanical and electrical properties, but it is often insufficient in terms of processability, solvent crack resistance and impact resistance. . As a method of solving these drawbacks, a method of mixing a polyphenylene ether resin and another resin such as a styrene polymer to improve the moldability is known from US Pat. No. 3,383,435.

ことを見い出し本発明を完成した。The present invention aims to improve this solvent crack resistance.
It has been considered that the oil resistance is improved by adding a polyolefin having good oil resistance such as polyethylene, polyester such as polyethylene terephthalate, and polyamide such as 6-nylon to the polyphenylene ether resin.
These have poor compatibility with polyphenylene ether, so that addition of a sufficient amount to improve oil resistance causes delamination of the molded product. The present inventor has found that, in addition to a resin mixture obtained by adding a polyamide to a combination of a polyphenylene ether resin and a styrene polymer, a graft type aromatic compound having a carboxyl group and / or an acid anhydride group in the trunk portion of the graft polymer. By adding a vinyl polymer,
The present invention has been completed by finding that a polyphenylene ether-based resin composition in which solvent crack resistance is remarkably improved without causing delamination, and surprisingly molding processability and rigidity are also improved, was obtained.
