Polycarbonates(PC) are thermoplastic materials with excellent transparency and high impact resistance, and cycloaliphatic polyesters, such as poly (1,4-cyclohexane-dimethylene-1,4-cyclohexane-dicarboxylate) (PCCD), have attracted more attention in the plastic industry because of their outstanding properties, such as weather-ability, chemical resistance, and resistance to UV radiation. A blend of polycarbonate and polyester is a polymer with high impact strength, improved chemical resistance, and excellent aesthetics. Our research focused on the analysis of the effect of ultrasonic irradiation on the polymer blend system. In this study, we produced the PC/PCCD blend by imposing ultrasonic energy or adding some catalyst during solution blending and compared each result of the blended polymer. The change of Tg (glass-transition temperature) and IR-spectrum were investigated with ultrasound-assisted blending. |
