Abstract
A composition of matter comprising: PA1 A) from 25 to 90 parts by weight of a syndiotactic, vinylaromatic polymer, PA1 B) from 5 to 30 parts by weight of an oil extended, elastomeric polyolefin; PA1 C) from 1 to 10 parts by weight of a compatibilizer comprising a styrene containing block copolymer or a hydrogenated derivative thereof; PA1 D) from 0 to 25 parts by weight of a domain forming rubbery polymer comprising a styrene/conjugated diene triblock copolymer or a hydrogenated derivative thereof; PA1 E) from 0 to 5 parts by weight of a nucleator for the syndiotactic, vinylaromatic thermoplastic resin, PA1 F) from 0 to 60 parts by weight of a reinforcing agent, and PA1 G) from 0 to 90 parts by weight of a polyarylene ether or polar group modified polyarylene ether.
