Solventresistant, compatible blends of polyphenylene ethers and polyesters.

摘要

Solvent-resistant resin blends with a wide variety of desirable impact and tensile properties are prepared from a polyphenylene ether having a low proportion of unneutralized amino nitrogen or a blend thereof with a polystyrene; an elastomeric polyester or a mixture thereof with a poly-(ethylene terephthalate) or poly(butylene terephthalate); and at least one elastomeric polyphenylene ether-compatible impact modifier. There may also be present a minor amount of at least one polyepoxide such as triglycidyl isocyanurate.
