ABSTRACT:
This invention relates to moulded, non-dusting, non-caking, free-flowing masticating agents based on 2,2'-dibenzamidodiphenyl disulphide and mixtures of saturated fatty acids having an iodine number <25, a solidification point in the range from 50.degree. to 68.degree. C. and an acid number of 179 to 215. The masticating agents according to the invention are employed for reducing the viscosity of rubbers containing double bonds, and are normally used in amounts of 0.01 to 3 parts by weight, based on 100 parts by weight of rubber.
