ABSTRACT:
Synthetic rubber compositions of improved green strength are prepared by reacting a rubbery polymer containing small amounts of tertiary amine groups bound in the polymer chain with a dihalogen compound having halogen groups located in the molecule of the compound in conjugated relationship to a carbonyl group. An example of a suitable rubbery polymer is a terpolymer of butadiene, styrene and dimethylanunoethyl methacrylate. An example of a suitable dihalogen compound is 4,4'-bis (bromoacetyl) diphenyl.
