摘要：

Cationically initiated copolymerization of carbazolyl oxiranes-9-(2,3-epoxypropyl)carbazole and 3,6-dibromo-9-(2,3-epoxypropyl)carbazole with tetrahydrofuran has been studied. Reactivity ratios of comonomers have been estimated. Carbazolyl oxiranes are more active monomers in these systems. Kinetics of copolymerization of carbazolyl oxiranes with tetrahydrofuran have been studied by calorimetric technique. The values of reaction orders with respect to concentration of the catalyst BF3Et2O and of activation energy have been estimated. Results on photosensitivity of electrophotographic layers based on these copolymers are presented.
