Reactivity of vinyl ethers and vinyl ribosides in UV-initiated free radical copolymerization with acceptor monomers.

The reactivity of various vinyl ethers and vinyloxy derivatives of ribose in the presence of diethyl fumarate or diethyl maleate was investigated for evaluating the potential of donor-acceptor-type copolymerization applied to unsaturated monomers derived from renewable feedstock. The photochemically induced polymerization of model monomer blends in the bulk state was monitored by infrared spectroscopy. The method allowed us to examine the influence of monomer pair structure on the kinetic profiles.

Compared reactivity of allyl ribosides in UV-initiated free radical copolymerization with acceptor monomers.

The free radical copolymerization of allyl ribosides with diethyl fumarate and maleate was investigated for evaluating the potential of donor-acceptor type copolymerization applied to unsaturated monomers derived from renewable feedstock. The photochemically induced polymerization of model monomer blends was conducted in solution as well as in liquid films of bulk reactants. Infrared spectroscopy was used to monitor the consumption of the allylic donor monomer and of the butenedicarboxylate acceptor monomers.
