ABSTRACT:
The green strength of synthetic elastomers is improved by forming copolymers from at least one type of various synthetic elastomer forming monomers with a hydroxyl containing monomer having the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are either hydrogen or a methyl group and R.sub.4 is an alkyl group having 1-10 carbon atoms and A is a methylene or carbonyl group. The green strength is further improved if a small amount of a hydroxyl ester cross-linking agent is utilized.
