ABSTRACT:
Polyesters or polyanhydrides are produced by reaction of non-conjugated dienes with diols or dicarboxylic acids, respectively, in the presence of a catalyst composition formed from a palladium compound, a monodentate phosphorus ligand optionally employed with a bidentate phosphorus ligand and a limited amount of a protonic acid having a pKa below 2, in the substantial absence of water. The polymer products are useful as constituents of sealants, adhesives and paints.
