Title:
透明なゴム変性共重合樹脂およびその樹脂組成物
Document Type and Number:
Japanese Patent JP4101175
Kind Code:
B2
Abstract:
The invention provides a rubber-modified copolymer resin which is excellent in transparency, impact resistance and rigidity and which has little dependency of the transparency on molding conditions, and a rubber-modified copolymer resin composition which has the above characteristics and which has high practical strength. A transparent rubber-modified copolymer resin which is a rubber-modified copolymer resin obtained by copolymerizing a styrenic monomer and a (meth)acrylic ester monomer in the presence of a rubbery polymer, and which is characterized in that the volume mean particle diameter of rubber particles dispersed in the resin, is from 0.4 to 2.0 mu m, and in the cumulative rubber particle size distribution curve by volume, the difference between the diameter at an integrated value of 75% and the diameter at an integrated value of 25%, is from 0.2 to 2.0 mu m; and a rubber-modified copolymer resin composition comprising from 60 to 99.9 mass% of the transparent rubber-modified copolymer resin (A) and from 0.1 to 40 mass% of an emulsion graft copolymer (B).
