Abstract:
PURPOSE: A transparent acrylonitrile-butadiene-styrene (ABS) resin composition is provided to have high transparency without lowering shock resistance and scratch resistance. CONSTITUTION: A transparent ABS resin composition comprises; (A) a acrylonitrile-butadiene-styrene copolymer in which a acrylate group monomer and the mixture (a2) of a styrene group monomer and a acrylonitrile group monomer are copolymerized on a butadiene group rubbery polymer (a1); and (B) a styrene-acrylonitrile copolymer. And the transparent ABS resin composition satisfies relation represented by chemical formula 1: 0
Abstract:
An acrylonitrile-styrene-acrylate (ASA) graft copolymer according to the present invention comprises: (A) a core layer including polymers polymerized by alkylacrylate monomers with a weight-average molecular weight of 200,000-10,000,000 g/mol; and (B) a shell layer including polymers polymerized by acylonitrile monomers and styrene monomers with a weight-average molecular weight of 50,000-500,000 g/mol. The core layer (A) is a triple core rubber polymer including: a first core layer formed by polymerizing alkylacrylate monomers; a second core layer formed by copolymerizing alkylacrylate monomers and styrene monomers on the first core layer; and a third core layer formed by copolymerizing alkylacrylate monomers and styrene monomers on the second core layer. The acrylonitrile-styrene-acrylate (ASA) graft copolymer of a core-shell structure has excellent impact resistance and dyeability.
