SYNTHESIS AND PROPERTIES OF CO-OLIGOMERS OF CARBAZOLYL OXIRANES AND TETRAHYDROFURAN

Cationically initiated copolymerization of carbazolyl oxiranes-9-(2,3- epoxypropyl)carbazole and 3,6-dibromo-9-(2,3-epoxypropyl)carbazole wit h tetrahydrofuran has been studied. Reactivity ratios of comonomers ha ve been estimated. Carbazolyl oxiranes are more active monomers in the se systems. Kinetics of copolymerization of carbazolyl oxiranes with t etrahydrofuran have been studied by calorimetric technique. The values of reaction orders with respect to concentration of the catalyst BF3E t2O and of activation energy have been estimated. Results on photosens itivity of electrophotographic layers based on these copolymers are pr esented.
