Abstract:
A rubber modified monovinylidene aromatic polymer composition comprisingI) a matrix comprising a monovinylidene aromatic polymer, and II) a rubber, in the form of dispersed rubber particles within the matrix, wherein the rubber particles are prepared from a blend of: a) from 75 to 25 weight percent based on the total weight of rubber, of a star branched diene rubber, having a cis 1,4 structure content of less than 75 percent; and b) from 25 to 75 weight percent, based on the total weight of rubber, of a linear diene rubber, having a cis 1,4 structure content of less than 50 percent; wherein the viscosity of the star branched diene rubber is less than the viscosity of the linear diene rubber.
