POLYLACTIC ACID RESIN COMPOSITION WITH EXCELLENT COMPATIBILITY, EXTERIOR APPEARANCE, HEAT RESISTANCE, AND MECHANICAL STRENGTH, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A polylactic acid resin composition is provided to have excellent compatibility, exterior appearance, processability, and decomposing performance, and to be applied to an electronic product and a vehicle interior.;CONSTITUTION: A polylactic acid resin composition comprises: a mixture which contains polylactic acid, an acrylonitrile-butadiene-styrene resin, and a styrene-acrylonitrile copolymer(SAN) resin; an alkyl(meth)acrylate based resin; and an impact reinforcing agent. The weight average molecular weight of the polylactic acid is 160,000-350,000. The polylactic acid is one or more selected from a poly L-lactic acid, poly D-lactic acid, and poly L,D-lactic acid.;COPYRIGHT KIPO 2013
