We introduce the
hybrid copolymerization of two disparate monomer
classes (vinyl monomers and ring-strained cyclic olefins) via living
photopolymerization. The living character of the polymerization technique
(metal-free photo-ROMP) is demonstrated by consecutive chain-extensions.
Further, we propose a mechanism for the copolymerization and analyze
the copolymer structure in detail by high-resolution mass spectrometry.
