ABSTRACT:
Novel linear alternating polymers wherein moieties derived from carbon monoxide alternate with moieties derived from a bicyclic unsaturated carboxylic acid or carboxylic acid anhydride, and optionally alternate with moieties derived from ethylene, and wherein at least a portion of the carboxylic acid or carboxylic acid anhydride functionality is present as higher alkyl ester, are produced by contacting carbon monoxide, bicyclic unsaturated carboxylic acid or carboxylic acid anhydride, and optionally, ethylene, under polymerization conditions in the presence of a higher alkanol and a catalyst composition formed from a palladium compound, the anion of a strong non-hydrohalogenic acid and a bidenate ligand of phosphorus.
