ABSTRACT:
Impact-resistant transparent polymeric compositions are prepared comprising particulate diene-monovinylidene aromatic block copolymer elastomer dispersed in a matrix comprising polymerized monovinylidene aromatic and acrylate monomers. These compositions can be advantageously prepared by adding the elastomeric block copolymer to an agitated polymerization system at a point where the elastomer will become dispersed as particles immediately or nearly immediately after addition.
