Document Type and Number:
WIPO Patent Application WO/2021/040269
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition comprising a (meth)acrylate graft copolymer, and a production method therefor, and more specifically, to a thermoplastic resin composition comprising a (meth)acrylate graft copolymer, and a production method therefor, the thermoplastic resin composition comprising A) a graft copolymer containing an alkyl acrylate rubber core and an alkyl methacrylate compound (co)polymer shell surrounding same, and B) a matrix resin, wherein: the rubber core has an average particle diameter of 40-100 nm; the A) graft copolymer has a degree of grafting of 20-100%; and the thermoplastic resin composition has a refractive index of above 1.46 to below 1.49, and a blackness L value of below 25.0. According to the present invention, the effect is achieved of providing: a thermoplastic resin composition comprising a (meth)acrylate graft copolymer, having good impact strength and excellent weather resistance, and especially expressing deep black well by having excellent coloring properties; and a production method therefor.
