Patent ID: 7019076

Claim:
A transparent rubber-modified copolymer resin composition, comprising: a rubber-modified copolymer resin, or a mixture of two or more rubber-modified copolymer resins, said resin(s) obtained by copolymerizing a styrenic monomer and a (meth)acrylic ester monomer in the presence of a particulate rubbery polymer, wherein the rubber particles dispersed in the resin have a volume mean particle diameter (dv) ranging from 0.4 to 2.0 μm, and wherein the particles of rubber are such that in the cumulative rubber particle size distribution curve by volume, the difference between the diameter (d75) at an integrated value of 75% and the diameter (d25) at an integrated value of 25% ranges from 0.2 to 2.0 μm, the resulting resin composition being transparent.
