ABSTRACT:
Effective bonding of a vulcanized composite of rubber to a brass coated steel cord is improved by the addition of small amounts of an organic polymer which contains polysulfide linkages in the backbone of the polymeric chain. Under conditions where heat and water ordinarily decrease the adhesion of the composite, rubber compounds with small amounts of the polysulfide have considerably increased adhesion to brass-plated steel cord.
