Abstract
The present invention provides a transparent thermoplastic resin composition which may comprise (A) about 1 to about 100 parts by weight of an ultra-high molecular weight branched acrylic copolymer resin; (B) about 0 to about 99 parts by weight of an acrylic resin; and (C) about 0 to about 40 parts by weight of an acrylic impact modifier, based on 100 parts by weight of (A) and (B). The ultra-high molecular branched acrylic copolymer resin (A) may be prepared by polymerizing a monomer mixture comprising (a1) about 50 to about 99.899% by weight of a mono-functional monomer, (a2) about 0.1 to about 40% by weight of a (meth)acrylic monomer having a flexible segment represented following Chemical Formula 1, and (a3) about 0.001 to about 10% by weight of a branch-inducing monomer. The thermoplastic resin composition of the present invention can have improved transparency, scratch resistance, flowability, and impact strength. wherein m is an integer from 3 to 18, Y is methyl or hydrogen, and X is methyl or hydrocarbon.
