Abstract
Rubber-modified monovinylidene aromatic copolymers having an enhanced combination of gloss, toughness and melt flow characteristics are provided by a process wherein a rubber latex having a specified particle size is partially agglomerated, emulsion graft polymerized to a specified graft copolymer to rubber (G/R) ratio and a specified graft copolymer molecular weight and further agglomerated during subsequent dewatering and/or melt compounding operations.
