POLYPROPYLENE CARBONATE POLYMETHYL METHACRYLATE MATERIALS IMPROVED IN TENSILE STRENGTH AND THERMAL STABILITY, AND THAT OF MANUFACTURING METHOD

摘要

The present invention relates to a polypropylene carbonate composite manufactured by adding maleic anhydride graft acrylonitrile-styrene copolymer to the blend of polypropylene carbonate, which is synthesized using carbon dioxide, and polymethyl methacrylate. The polypropylene carbonate composite according to the present invention can be applied to molded products requiring impact resistance, high tensile force, etc., can be manufactured at low costs, and is eco-friendly as the polypropylene carbonate composite has increased tensile strength, excellent dispersibility and excellent thermal stability while maintaining the characteristics of polypropylene carbonate with flexibility and excellent processability.
