Abstract
Polymerization of a bifunctional monomer, 4-methylene-2-phenyl-2-(4-vinylphenyl)-1,3-dioxolane (3), is described. 3 is anticipated to undergo polymerization of the styrene moiety, addition polymerization of the unsaturated cyclic monomer moiety, and elimination polymerization with formation of benzophenone derivative. However, selective polymerization of the styrene moiety of 3 is achieved in DMF solution, with complete retention of another radical polymerizable group as a pendant on side chain. Furthermore, bulk polymerization gave a crosslinked polymer and low concentration reaction caused back biting of its own side chain.
