Abstract
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.
