ABSTRACT:
Substantially alternating, organic solvent soluble copolymers of 2000 to 4000 molecular weight useful as crosslinking agents and containing monomeric units derived from monomers comprising (i) 40 to 50 mole percent of an isopropenyl-.alpha.,.alpha.-dimethylbenzyl isocyanate, and (ii) 60 to 45 mole percent of an unsaturated ester are described together with processes for their preparation. Curable compositions containing the copolymer and an isocyanate reactive material are also described.
