A RUBBER REINFORCED THERMOPLASTIC RESIN COMPOSITION HAVING HIGH IMPACT STRENGTH AND GOOD COLORABILITY

摘要

PURPOSE: A rubber reinforced thermoplastic resin composition is provided to improve colorability, shock resistance, and transparency by selectively introducing seed particles containing copolymers of two or more polymers with different chemical structures to the surface of a diene-based polymer. CONSTITUTION: A rubber reinforced thermoplastic resin composition comprises (A) 10-40 weight% of graft-copolymer and (B) 60-90 weight% of thermoplastic copolymer. The graft-copolymer comprise 40-80 weight% of diene-based rubber polymers, 5-50 weight% of aromatic vinyl monomers, and 5-40 weight% of vinylcyan monomers, (meth)acrylic acid ester monomers, or their mixture.
