Abstract
A novel thermoplastic resin polymer comprising a polyphenylene ether (POE) and a low molecular weight styrene polymer bonded to the PPE in an amount of from 0.1 to 5.0% by weight based on the PPE has been found to have excellent moldability and thermal stability properties, while maintaining the excellent properties inherent in PPE, such as transparency and heat resistance. The resin polymer can be prepared from a polyphenylene ether and a styrene monomer by polymerization in the absence of a radical polymerization initiator. When the novel thermoplastic resin polymer and a styrene polymer are blended into a composition, the composition is particularly excellent in physical properties, such as moldability, color tone, impact resistance, elongation and surface gloss.
