Abstract
The present invention provides compositions which comprise a blend of: p0 (a) from about 10 to about 97 percent by weight of the composition of a polyamide resin having a minimum molecular weight of about 5,000; p0 (b) from about 3 to about 90 percent by weight of the composition of an elastomeric polymer which PA1 (1) is selected from a group consisting of poly(ethylene oxide), poly(propylene oxide), polycaprolactone, polytetrahydrofuran, polybutadiene, polyisoprene, polyisobutylene, poly(C.sub.1 -C.sub.8 alkylene acrylate), poly(C.sub.1 -C.sub.4 dialkylene siloxane), poly(ethylene-co-propylene), poly(ethylene-co-carbon monoxide), polyethylene-co-vinyl chloride, and poly(ethylene-co-vinyl acetate) polymers and copolymers and combinations thereof; and PA1 (2) contains a minimum of about 0.055 milliequivalents of acyllactam groups per gram of said elastomeric polymer.
