Abstract
Impact modifiers which produce transparent, high notched Izod impact strength blends with amorphous, aromatic polyesters are described. The impact modifiers are core-shell polymers with cores comprised mainly of rubbery polymers of diolefins and vinyl aromatic monomers and shells comprised mainly of styrene copolymers (e.g. styrene and hydroxyalkyl (meth)acrylate).
