ABSTRACT:
A copolymer and a process of making the copolymer are disclosed. The copolymer is produced from reacting a glycidyl ester and/or ether with a polyol comprising a functionality of at least 2 wherein at least 50% by weight of the copolymer comprises a minimum of 3n+X repeating units, wherein n is a monomer unit and X is a monomer unit and/or other reactant. The copolymer may also include less than 50% of the polymeric units having the same molecular weight. The present invention is further directed to processes for preparing the copolymer and to coating compositions employing the copolymer.
