Procedure

A chloroprene/methyl methacrylate graft copolymer was prepared as follows. A mixture of 80 parts chloroprene, 20 parts methyl methacrylate, and 0.2 parts n-dodecylmercaptan was emulsified with 110 parts water, 5 parts 60% triethanolammonium dodecylbenzene sulfonate, 1 part nonyl phenol condensed with 10 moles of ethylene oxide, 0.3 parts sodium sulfite, and 0.24 parts potassium hydroxide. Polymerization was initiated at 15° C. by addition of potassium persulfate and the temperature was maintained until the specific gravity of the emulsion reached 1.060 B which represented a conversion of 75%. The temperature of the emulsion was then raised to 48° C. and polymerization continued until no further specific gravity increase was observed. The conversion was greater than 99% and a shortstopping agent, phenothiazine, was added. The solids content of the emulsion was 47.0%.
