<p>PURPOSE: An environment-friendly thermoplastic resin composition is provided to improve environment-friendly contamination load without degrading mechanical properties or flowability of an ABS resin. CONSTITUTION: An environment-friendly thermoplastic resin composition comprises 20-80 parts by weight of a rubber-modified graft copolymer, and 20-80 parts by weight of an acrylic copolymer, and 10-30 parts by weight of biodegradable polylactic acid. The polymerization conversion rate of the acrylic copolymer is 70-80 %, the total solid content is 55-65 %, and the weight average molecular weight is 90,000-100,000. The polylactic acid resin comprises 60 mol% or more of L-isomer and has a weight average molecular weight of 10,000-400,000.</p> |
