Abstract:
1. A transparent thermoplastic resin composition comprising: (A) about 1 to about 100 parts by weight of an ultra-high molecular weight branched acrylic copolymer resin, wherein said ultra-high molecular branched acrylic copolymer resin (A) is prepared by polymerizing a monomer mixture comprising (a1) about 50 to about 99.899% by weight of a mono-functional monomer, wherein said mono-functional acrylic monomer (a1) comprises methyl methacrylate, ethyl methacrylate, propyl methacrylate, methyl acrylate, ethyl acrylate, propyl acrylate, 2-ethyl hexyl acrylate, 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, monoglycerol acrylate, maleic anhydride, or a combination thereof, (a2) about 0.1 to about 40% by weight of a (meth)acrylic monomer having a flexible segment represented by the following Chemical Formula 1, and (a3) about 0.001 to about 10% by weight of a branch-inducing monomer; wherein: m is an integer from 3 to 18, Y is methyl or hydrogen, and X is methyl or hydrocarbon; and (B) about 0 to about 99 parts by weight of an acrylic resin.
