THERMOPLASTIC RESIN COMPOSITION

摘要

PURPOSE: A thermoplastic resin composition is provided to ensure excellent appearance properties such as colorability and glossiness, hardness, scratch resistance and weather resistance by controlling a glass transition temperature of polymer seeds, the content of acryl rubber latex and the composition of a monomer. CONSTITUTION: A thermoplastic resin composition comprises 6 - 60 weight% of a first core-shell graft-copolymer and 40 - 94 weight% of a copolymer formed by polymerizing (meth)acrylic acid ester monomer, aromatic vinyl monomer, and vinylcyan monomer. The first core-shell graft-copolymer is such that the aromatic vinyl monomer and vinylcyan monomer are grafted to an acryl rubber latex including hard polymer seeds with average particle diameter of 200 - 500nm.
