    Abstract: A composition comprises an ethylene-propylene copolymer rubber and a fusible, nonheat hardenable, novolak resin of formaldehyde and a phenol of formula wherein R1 is a monovalent cyclic hydrocarbon radical, R2 is a divalent alkylene radical containing 1 to 6 carbon atoms, and n is 0 or 1. In the examples, the rubbers used are ethylenepropylene copolymer and ethylene-propylenebutadiene terpolymer; and the novalak resins are phenylethylphenol-formaldehyde, p-cyclopenten-2-ylphenol-formaldehyde, and p-phenylphenol-formaldehyde resins. Optional ingredients are conventional rubber additives, in particular carbon black. The vulcanization of a composition of the invention is illustrated using dicumyl peroxide and sulphur. The products find application in tyres, cable coatings and adhesives.
