POLY(ARYLENETHER)POLYOLEFINZUSAMMENSETZUNG SOWIE VERFAHREN DAFÜR UND ARTIKEL DARAUS

摘要

A thermoplastic composition includes the product of melt kneading a composition including a poly(arylene ether), a polyolefin, and a high molecular weight hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene. The composition exhibits substantially improved chemical resistance compared to a corresponding composition prepared with a lower molecular weight hydrogenated block copolymer. Methods of preparing the composition and articles prepared for the composition are also described. The composition is particularly useful for fabricating halogen-free tubes for sheathing automotive wiring harnesses.
