ABSTRACT:
Synthetic rubber compositions of improved green strength are prepared by incorporating in a synthetic rubber polymer, such as NBR or SBR, a small number of tertiary amine groups, and reacting this polymer with a halogen compound containing two or more halogen atoms capable of forming quarternary ammonium salts with the tertiary amine groups on the polymer. 1,4-dibromobutene-2 is a suitable halogen compound. The tertiary amine groups can be incorporated by copolymerizing dimethylaminoethyl acrylate with the rubbery copolymer forming monomers.
