Problems solved by technology

However, due to the low impact strength of butyl acrylate impact modifiers, large amounts of butyl acrylate impact modifiers must be used
As a result, the natural performance of (meth)acrylate resins is deteriorated

Embodiment 1 to 7 and comparative example 1 to 5

[0032] As a base resin, poly(methyl methacrylate-phenyl methacrylate) copolymers according to the compositions summarized in Table 1 (Example) and Table 2 (Comparative Example) below were prepared. Properties (pencil hardness, molecular weight (weight average molecular weight) and glass transition temperature) of the prepared poly(methyl methacrylate-phenyl methacrylate) copolymer were measured. Next, impact modifiers were mixed according to the compositions summarized in Tables 1 and 2 below, and samples of the resin compositions were prepared by injection molding. The properties (pencil hardness, fluidity, impact strength and transparency (haze value)) of the prepared samples were measured. The results are summarized in Tables 1 and 2.

[0033] Impact modifier 1 in Tables 1 and 2 below is an ABS-based graft copolymer as a core-shell type (butadiene rubber exists as a core) butadiene-based polymer, which is obtained by emulsion polymerization according to the present inventi...

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...
