Cationic photoinitiated copolymerization of 1-propenyl–vinyl ether systems

A kinetic investigation of the photoinitiated cationic copolymerization of 1-propenyl ethers with vinyl ethers monomers was performed by using FT-IR and 1H-NMR analysis. FT-IR results, obtained in bulk, indicate a higher reactivity of the vinyl ether with respect to the 1-propenyl ether double bond. 1H-NMR analysis, in CDCl3 solution, confirms these results which agree with the literature data concerning monofunctional systems. The properties of the UV cured copolymerization products are investigated by DMTA analysis and discussed on the basis of the kinetic investigation results.
