Abstract
In the process disclosed herein, a latex comprising a diene rubber pregrafted with styrene/acrylonitrile type monomer mixtures, for example, about 5 to 50% by weight styrene/acrylonitrile emulsion-grafted thereon, is added to an aqueous solution of suspending agent. Additional styrene/acrylonitrile type monomers are then added to the dispersion and polymerized onto the suspended rubbery particles with peroxide initiator to produce ABS type polymers containing from about 3 to less than about 30 percent by weight diene rubber.
