Abstract
Reaction products of phenol and hexamethylenetetramine act as methylene donors in rubber compounds containing acceptors such as free resorcinol or precondensed resorcinol-formaldehyde (RF) resins. The products of reaction between this methylene donor and various methylene acceptors produce excellent adhesion between the rubber compounds and reinforcing substrates. Reinforcement of the rubber compound is obtained and this donor does not cause degradation of polyester cord used as a reinforcing substrate.
