摘要
The present invention is a rubber modified monovinylidene aromatic polymer having a bimodal particle size distribution comprising: a) rubber particles of a star or branched low viscosity rubber having a volume average particle size of from 0.1 to 2mu, and a cellular or core shell morphology or mixture thereof, and b) rubber particles of a star or branched low viscosity rubber, linear diene rubber or block copolymer rubber having a volume average particle size of from 0.5 to 10mu, characterized in that the rubber particles of b) are more dense than the rubber particles of a), having a smaller occluded monovinylidene aromatic polymer content than the particles of a), wherein the particles of a) are from 50 to 99 weight percent of the total diene rubber content
