POLYLACTIC ACID RESIN WITH EXCELLENT IMPACT RESISTANCE AND HEAT RESISTANCE WHILE MAINTAINING ENVIRONMENTAL-FRIENDLY PROPERTY AND A MOLDED PRODUCT USING THE SAME

摘要

PURPOSE: A blend of a polylactic acid resin and copolymerization polyester resin is provided to maintain content of polylactic acid resin and isosorbide over a specific amount, thereby improving impact resistance and heat resistance of a polylactic acid resin.;CONSTITUTION: A blend of a polylactic acid resin and a copolymerized polyester resin comprises a polylactic acid resin; a copolymerized polyester resin including a diol component and dicarboxylic acid component with a terephthalic moiety. The diol component comprises 3-99 mol% of a cyclohexanedimethanol moiety and 1-60 mol% of an isosorbide moiety. The moiety of isosorbide moiety in the copolymerization polyester resin is 60-95 wt%.;COPYRIGHT KIPO 2013
