Problems solved by technology

[0002] Polycarbonate (PC) has good mechanical strength, impact resistance and dimensional stability, but polycarbonate has poor processing fluidity, poor chemical resistance, and is prone to stress cracking, so polycarbonate is subject to greater application restrictions
However, PC is modified by mixing resin plastics such as PP and PET with PC, but the compatibility of mixing PC with PP and PET is poor, and a large amount of compatibilizer or toughening agent needs to be added to improve the stability of PC. Comprehensive performance increases the production cost, and the impact strength, toughness, heat resistance, processing performance and other properties are low, which cannot meet the needs of electronic appliances, medical equipment, mechanical equipment and other fields
