Abstract

A halogen-free self-extinguishing thermoplastic composition comprising as the flame retardant, one or more phosphorus-containing compounds or elemental phosphorous, a polyphenylene ether, a styrene-acrylonitrile copolymer, a phenol/aldehyde resin, a terpolymer of styrene, acrylonitrile and a hydroxy-containing ester of acrylic or methacrylic acid on which a polyphenylene ether is grafted, and optionally, a diene elastomer having grafted thereon styrene and acrylonitrile monomers.
