COPOLYMERIZATION OF (p-VINYLPHENYL)CYCLOPROPYLMETHYLCINNAMATE WITH GLYCIDILMETHACRYLATE

摘要

The radical copolymerization of (p-vinylphenyl) cyclopropylmethylcinnamate with glycidilmethacrylate has been studied. New cyclopropane- and epoxycontaining photosensitive copolymers have been prepared. The constant values of relative activity of monomers have been determined and the parameters of Q-e on Alfrey and Price have been determined. The copolymerization constants of the given compound (r 1 ) with glycidylmethacrylate (r 2 ) calculated on Fineman-Ross method are: r 1 = 1.05, r 2 = 0.4 correspondingly? the parameters values Q and e: Q 1 = 1.82, e 1 = -0.79 correspondingly. The composition and structure of this copolymer has been established. The photochemical investigations of the synthesized copolymer have been carried out. It has been established that the structuring proceeds due to cyclopropane ring opening and epoxide groups and also double bond in cinnamate fragment.
