    摘要: Synthetic elastomer compositions of high green strength comprise the reaction product of a rubbery polymer of a conjugated alkadiene having a small number of aldehyde groups attached to and randomly distributed along the polymer chain, and a polyamine having at least two non-tertiary amine groups. An example is a copolymer of styrene, butadiene and cinnamaldehyde (0.5 parts by weight) reacted with p-phenylene diamine, in an amount of 1 mole diamine per mole of cinnamaldehyde.

    摘要: A process is provided for the polymerization of butadiene-1,3 to yield a high cis-1,4-polybutadiene in which the diluent for the polymerization is a mixture of cyclohexane and either or both of benzene and butene-1, wherein the amount of benzene is markedly reduced in comparison with that generally used. The polybutadiene may be used in the manufacture of tires and in impact polystyrene.

    摘要: 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.
