“…This is easily can be realized only in a case of cationic polymerization of vinylcyclopropyl ether (VCPE) and its derivatives [6]. In particular, the polymers containing macromolecules of gem-dichlorocyclopropyl groups in the side chain, prepared on the basis of vinylbutyl or vinyl-gemdichlorocyclopropyl ether in the presence of trifluoride boron etherate in hexane solution, possess bactericide properties [7]. In addition, it has been also detected the antiblastic action previously unknown for representatives of this class of compounds, which shows a perspectivity of further searches in series of new substances.…”
