Abstract
Butadiene polymer rubber compositions containing a polymeric activator have particularly beneficial characteristics. The activator is an interpolymer of a vinylpyridine monomer and a diene hydrocarbon monomer which interpolymer contains from 20% to 65% by weight of vinylpyridine units. Composite articles made from these rubber compositions together with contiguous portions of a dissimilar rubber compound show greater strength and adhesion as a result of the presence of a activator in the butadiene polymer rubber composition.
