AbstractThe present invention discloses production process of impact-resisting and heat resistant copolymerized resin. By combining suspension polymerization and emulsion polymerization, emulsion is first prepared through emulsion polymerization, rubber phase is then prepared through emulsion coaglomeration, and dispersant and monomer for copolymerization are added directly for suspension polymerization without passing through drying. The present invention has the optimized ratio between the rubber phase and the monomer for copolymerization of 10-30 wt% to 70-90 wt%. The impact-resisting and heat resistant copolymerized resin has both impact resisting performance and heat resistant performance of PVC.
