摘要

Disclosed herein are random graft copolymer compositions comprising base polymers that are amorphous to x-rays at a temperature of 130 DEG C. or below, to which base polymer is randomly grafted, on the average, at least one sidechain of crystallizable homopolymers, of alpha -substituted- beta -propiolactones and/or copolymers thereof; a process for making said random graft compositions; and use thereof, inter alia, as molded or extruded articles.
