Vinyl trans‐cinnamate, an unsymmetrical divinyl monomer, has been synthesized, and polymerized to linear, soluble polymers. It was found by infrared and chemical analysis that these polymers are quite different from polyvinyl cinnamates synthesized through esterification of polyvinyl alcohol by cinnamoyl chloride. The polymers prepared by polymerization of the monomer are characterized by the presence of γ‐lactone rings resulting from a cyclopolymerization mechanism.
