(Meth)acrylate resin composition having excellent impact resistance and transparency

Abstract

Disclosed is a (meth)acrylate-based resin composition comprising a poly(alkyl(meth)acrylate-phenyl(meth)acrylate) copolymer comprising phenyl(meth)acrylate having excellent surface hardness and a high refractive index, as a base resin and a (conjugated diene (meth)acrylate) graft copolymer having excellent impact absorption efficiency, the (meth)acrylate-based resin composition providing excellent transparency by exhibiting excellent impact resistance even using a small amount of impact modifier. The (meth)acrylate-based resin composition having excellent impact resistance and transparency comprises 1 to 29 wt % of the (conjugated diene-(meth)acrylate) graft copolymer and 71 to 99 wt % of the poly(alkyl(meth)acrylate-phenyl(meth)acrylate) copolymer.

Description

technical field

[0001] The present invention relates to a (meth)acrylate resin composition having excellent impact resistance and transparency. More specifically, the present invention relates to a (meth)acrylate resin composition comprising poly(alkyl(meth)acrylate-phenyl(meth)acrylate) copolymer as a base resin and A conjugated diene polymer having excellent impact absorption rate as an impact modifier, the poly(alkyl(meth)acrylate-phenyl(meth)acrylate) copolymer contains excellent surface hardness and A high refractive index phenyl (meth)acrylate, the (meth)acrylate resin composition provides excellent transparency by exhibiting excellent impact resistance even with a small amount of impact modifier. Background technique

[0002] (Meth)acrylate-based resins have excellent transparency and weather resistance, and excellent hardness, chemical resistance, surface gloss, adhesiveness, etc., and thus are widely used as glass substitutes. Currently, (meth)acrylate-based resin...
