METHOD OF PROCESSING POLYCARBONATE AND ACRYLONITRILE-BUTADIENE-STYRENE BLEND AT HIGH SHEAR RATES

摘要

The present invention relates to a method of processing a polycarbonate (PC) resin and acrylonitraile-butadiene-styrene (ABS) resin at high shear rates, where a phosphoric acid-based compatibilizer is added. A PC/ABS blend processed by the method of the present invention exhibits no degradation in physical properties due to a phase separation phenomenon to be employed in wide commercial applications. The method according to the present invention may be a method of processing a PC/ABS blend at high shear rates under a rotary velocity of 500-3000 rpm and a temperature of 200-250°C after mixing with 0.01-10 parts by weight of a diphosphate-based compatibilizer, with respect to 100 parts by weight of a PC/ABS blend.;COPYRIGHT KIPO 2015
