Polycarbonate was one of the materials which has the highest impact strength in the high polymer materials. However, there was a problem that impact strength decreased in low-temperature environment. S In order to solve this problem, PC which copolymerized the poly dimethyl siloxane was developed. In this study, change by the load rate of impact strength was verified about PDMS-PC. By preserving ductile fracture, PDMS-PC had controlled the decrease in fracture energy.
