Radical copolymerization of (p-vinylphenyl)cyclopropylmethyl cinnamate with styrene was studied. A new cyclopropane-containing photosensitive copolymer was prepared. The composition and structure of the synthesized copolymer and the relative activity constants of the monomers were determined, and the Q-e parameters were calculated. The dependence of the photosensitivity on the copolymer composition was revealed.
The paper deals with obtainment methods of formaldehyde and alternative ecological fuel types – dimethyl ether and dimethoxymethane. The development studies of these products were carried out both on Zr-Mo, Zr-V, V-Fe bimetallic catalysts and modified Со2+, Сu2+ forms of clinoptilolit. The optimum conditions of reaction conducting have been studied, RFA and RFES specters of the catalysts took, and the connection between the composition of surface layer and catalysts’ activity and selectivity specified as well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
