Procedure

70 g styrene, 30 g butyl acrylate, 5 g sodium stearate, 0.8 g divinyl benzene, and 200 g water deionized by ion exchange resins are mixed and placed in a polymerization vessel. To the resulting mexture are added 4 g n-dodecyl-mercaptan and 0.2 g K2S2O8 followed by emulsion polymerization for 15 hours at 50° C. to give a styrene-butyl acrylate-divinyl benzene copolymer.
