High-temperature copolymerization of ethyl esters of vinyl-or isopropenylcyclopropanecarboxylic acids with SO 2 was studied as a route to functionally substituted unsaturated polysulfones. The composition, structure, and some properties of the polysulfones obtained were studied. The copolymerization mechanism was considered.Copolymers of olefins with SO 2 , polysulfones (PSs), show much promise for practice [133]. In particular, they can be used as plastics, materials for concentrating sulfuric acid solutions [1], and coatings for fabrics, paper, and wood [2]. Polysulfone materials are used for insulation and soundproofing. Polysulfones prepared from SO 2 and higher olefins improve the viscosity index of hydrocarbon lubricants [3].
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.
