Abstract

A process for producing elastomeric polymers which comprises polymerizing in an aqueous emulsion at least one conjugated diene containing four to twelve carbon atoms, or mixtures of at least one such conjugated diene and at least one monomer containing a vinylidene group in the presence of an open-chain saturated mercaptan containing 8 to 10 carbon atoms or an unsaturated cyclic mercaptan containing from 10 to 12 carbon atoms and one or more olefinic bonds in non-conjugated arrangement and separated by at least two carbon atoms, the mercaptan having a solubilization rate, in an aqueous soap solution of 2.5 to 3.0 weight per cent, of at least 19 x 10-4 g./cm.2/hr. and a depletion rate during polymerization such that not more than 15 weight per cent of the total mercaptan is unreacted at 40% monomer conversion, at least 60% of the mercaptan being introduced at the beginning of the reaction and the remainder being added in one or more increments after about 7% monomer conversion and before 40% conversion. Specified mercaptans are tert.-octyl, tert.-nonyl, 2-nonyl, 4-nonyl, tert.-decyl, 2-decyl, 5-decyl, 4-cyclodecenyl and cyclododecadienyl mercaptans. The elastomers may be polymers of butadiene, isoprene, 2,3-dimethyl butadiene, piperylene, 2-methyl-hexadiene, chloropene, methoxy butadiene and cyanobutadiene or their copolymers with styrene, 3-vinyl toluene 1- or 2-vinylnaphthalene, 3-methylstyrene, 2-methyl-5-vinyl-pyridine, acrylonitrile, methylacrylate or methyl vinyl ether. The usual emulsifiers, catalysts &c. may also be present.
