Abstract
Dimethacrylate esters of a diol are linearly copolymerized by step dimerization of methacrylate groups of a dimethacrylate ester in the presence of a non-peroxide free radical initiator and a Cobalt (II) catalyst complex for chain transfer to monomer to produce a linear polyester polymer having 2,2-dimethyl-4-methylene glutarate structural units in the polymer chain.
