SOLVENT-RESISTANT COMPATIBLE COMPOUND OF POLYPHENYLENE ETHER AND THERMOPLASTIC POLYESTER

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; a poly(ethylene terephthalate), poly(butylene terephthalate), elastomeric polyester or mixture thereof; at least one elastomeric polyphenylene ether-compatible impact modifier and at least one polymer containing a substantial proportion of aromatic polycarbonate units as a compatibilizing agent. There may also be present a minor amount of at least one epoxide such as triglycidyl isocyanurate.
