Abstract

100 parts by weight of chloroprene are copolymerized with 1.5 to 30 parts of 2,3-dichlorobutadiene and 1 to 50 parts of styrene. The monomers are copolymerized in aqueous emulsion using the sodium salt of disproportionated wood rosin as emulsifying agent, the sodium salt of a formaldehyde/sodium naphthalene sulphonic acid as dispersing agent, potassium persulphate as catalyst and in the presence of N-dodecylmercaptan. The polymerization is terminated by adding either phenothiazine or p-tert-butyl catechol. The latex formed is coagulated and recovered by conventional means.
