ABSTRACT:
Prevulcanization of elastomer is inhibited by incorporation into the elastomer to be vulcanized, a minor amount of certain methyl substituted-aminoalkyl phenols as inhibitors or scorch retarders, and at least one of a polyfunctional (meth)acrylic monomer, allylic compound, or metal salt of unsaturated monocarboxylic acids which provides improved technical advantages as a reactive coagent in the cross-linking of such elastomeric compositions.
