ABSTRACT:
Vulcanizable rubber compositions are disclosed which contain co-activator of vulcanization which is a polymeric amine, that is, a hydrocarbon polymer with pendent alkyl amine groups. The co-activators impart increased rates of vulcanization with little decrease in scorch delay and very little increase in the modulus of the cured compositions. No increase in heat build-up or decrease in flex-fatigue life is shown. Typical polymers forming the backbone of the co-activators include EPDM rubber and polymers from butadiene or isoprene, with optional co-monomers.
