Title  Polymer composites that can be extruded and injected  at low temperature                      

Abstract

This study prepared a kind of polymer composites. The composite material has good processing performance and can be extruded and injected at low temperature. This polymer composite material obtained by extrusion a mixture which consiste of copolymer resin, ablation resistance fillers, plasticizers and other additives. The preparation of the composite material includes: First, preparation of the special resin for the composite materials, the special resin is butyl methacrylate/styrene copolymer obtained by suspension polymerization method. Second, the preparation of methyl silicone resin and silicone rubber of core-shell structure. Methyl silicone resin prepared by Methyl trimethyl silane via hydrolytic condensation while emulsion polymerization method was used to prepare silicone rubber of core-shell structure. Third, the copolymer was blended with silicone rubber of core-shell structure, methyl silicone resin and other additives, then extruded and injected the mixture. Test its mechanical properties, thermal stability and processing performance at low temperature.

Keywords  Polymer composites, silicone rubber of core-shell structure, BMA, processing performance at low temperature
