Abstract
Disclosed herein is a latex polymerization process for grafting styrene and acrylonitrile type monomers onto a rubber latex which has been stabilized with a substance which inhibits polymerization. The process involves carrying out the graft polymerization reaction in the presence of from 1 to 10 parts of latex seed particles per hundred parts of rubber using a chain transfer agent that doesn't inhibit the graft polymerization reaction.
