A process for preparing impact resistant styrenic resins comprises; a) adding a monomer or monomer mixture capable of forming a rubbery polymer by polymerization (preferably comprising an acrylic acid ester) to a suspension of beads of a polymer of a styrenic compound; b) contacting the beads and the monomer material under conditions in which said monomer is absorbed by said beads and c) suspension polymerizing said monomer material with formation of a rubbery polymer partly grafted on the polymeric beads. The resulting styrenic resin exhibits good impact strength and gloss. |
