    摘要: Disclosed herein is a method for evaluating scratch resistance of a plastic resin comprising scratching a surface of a test sample of plastic resin using a scratch apparatus to form a scratch of the surface having a scratch profile; scanning the scratched test sample with a surface profile analysis apparatus to measure the scratch profile; and creating a scratch resistance evaluation index based on the measured scratch profile to evaluate the scratch resistance of the test sample. The method has good reliability and reproducibility, reduces measurement time and errors caused by measurers and measuring conditions, provides easy measurement and can be widely applied to all plastic resins.

    摘要: 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.
