THERMOPLASTIC RESIN COMPOSITION AND THERMOPLASTIC RESIN COMPOSITION HAVING HIGH RE-SCRATCH PROPERTY WITH LOW YELLOWNESS

摘要

PURPOSE: An alkyl(meth)acrylate-based thermoplastic resin composition is provided to reduce the total content of a vinylcyan-based monomer in the resin composition and to obtain improved scratch resistance and low yellowing property while maintaining transparency, flowability, and impact strength. CONSTITUTION: An alkyl (meth)acrylate-based thermoplastic resin composition consists of 70-90 weight% of a bulk polymer and 30-10 weight% of a graft copolymer each of which comprises an alkyl(meth)acrylate-based monomer. The graft copolymer comprises 0.01-3 weight% of a vinylcyan monomer based on the total weight of the alkyl(meth)acrylate-based thermoplastic resin composition. The bulk polymer is obtained by bulk-polymerizing 60-80 weight% of an alkyl(meth)acrylate-based monomer and 20-40 weight% of an aromatic vinyl monomer in a reaction medium.
