Abstract
A process for the production of a moldable thermoplastic having enhanced resistance to impact, and the resulting product, is disclosed. A cross-linked bulk cast elastomer including a graft-linking agent is produced and is then finely divided and compounded with a catalyzed polymerizing monomer mixture, which may also include a minor proportion of a graft-linking co-monomer. Graft-linking of the elastomer to the resulting polymer occurs in situ; and the mass of the elastomer graft-linked to the polymerizing monomer is then compounded with a moldable matrix polymer and the compounded blend is then extruded through a die.
