Abstract

The photo‐induced “charge‐transfer” copolymerization of various donor monomer‐acceptor monomer pairs was studied by irradiation of their CT complexes with 365 nm light. The influence of the donor and acceptor strength on the rate of polymerization shows that stronger donor/weaker acceptor pairs or weaker donor/stronger acceptor pairs favor copolymerization. The proposed initiation mechanism involves the formation of an excited complex, which then collapses to the tetramethylene diradical for initiation of free radical copolymerizations.
