Abstract
The use of C.sub.10 to C.sub.14 alkanoic acids, especially lauric acid, as a processing aid in the vulcanization of polychloroprene rubbers by heating in the presence of magnesium oxide, zinc oxide and thiophosphoric-N,N',N"-trimethyltriamide. Also the manufacture of pre-formed mixtures of the acid and the amide in the ratio of 0.5:1 to 2:1 for use in this process. The use of these acids overcome the technical problem of blooming on storage which is obtained when the more usual stearic acid is used in the process.
