Beschreibung
Zusammenfassung:	High impact strength resin compositions and methods of preparations thereof. The compositions contain at least 60% polyamide together with an elastomer and a polymeric emulsifier. The elastomer is preferably a copolymer of ethylene and an acrylic ester, and the emulsifier is preferably an ethylene/acrylic ionomer with at least about 50% of the carboxyl groups neutralized by displacement of a proton with a metal ion. In a particularly preferred embodiment, the polyamide is dispersed in a continuous elastomeric phase.
