Abstract
Abstract DISCLOSED HEREIN ARE MATRIX POLYMERS AND COPOLYMERS REINFORCED WITH IN SITU FORMED POLYMERIC FIBERS OF HIGH SOFTENING POINT. THESE FIBERS ARE INTRODUCED INTO THE MATRIX POLYMER BY MEANS OF A POLYMERIC CARRIER HAVING A HIGH HEAT STABILITY AND A LOW FLOW TEMPERATURE RELATIVE TO THE MATRIX POLYMER. COMPOSITIONS FORMED THEREBY CAN BE MOLDED INTO ARTICLES HAVING INCREASED RESISTANCE TO DEFORMATION UNDER LOAD AT HIGH TEMPERATURES. THE MATRIX RESIN MAY BE EITHER POLYVINYL CHLORIDE OR AN ACRYLONITRILBUTADIENE-STYRENE RESIN. THE CARRIER POLYMER IS EXEMPLIFIED BY A STYRENE-ACRYLONITRILE INTERPOLYMER REINFORCED WITH ANY OF POLYCARBONATE, NYLON 66, OR POLYOXYMETHYLENE.
