More Information
Summary:A method is described whereby olefin terpolymers, consisting of ethylene, an alpha olefin and a polyene having in the molecule, in addition to the double bond participating in the formation of the macromolecule, at least one conjugated double bond system, are stabilied against oxidative aging without destroying their characteristic high vulcanization rate by reacting them with a dienophilic agent represented by one of the following formulae: WHEREIN R and R6 may be an alkyl, alkenyl, cycloalkyl, aryl or aralkyl radical having up to 8 carbon atoms, R1, R2, R3, R4 and R5 may be hydrogen or alkyl, aryl, cycloalkyl or aralkyl radicals having up to 8 carbon atoms, the R1-R2 and R-R pairs may be divalent radicals forming condensed rings.
