Abstract
Functionalized thermoplastics such as styrene-maleic anhydride copolymers or maleated polyolefins may be toughened with halogenated rubbers which are copolymers of isoprene and isobutylene provided a dialkyl or dihydroxyalkyl amino alkanol is present as a compatibilizer. The toughened thermoplastics have about a two fold increase in IZOD impact resistance.
