Summary
The copolymerization of 2-(9-carbazolyl)ethylmethacrylate, 3-(9-carbazolyl)propyl-2-methacrylate and 2-(9-carbazolyl)ethylacrylate with methacrylic acid has been studied obtaining the reactivity ratios of the monomers in benzene. For the estimation of molar masses and copolymer compositions esterification of the copolymers has been performed. A thermal study of the obtained copolymers related to the carbazolylalkyl(meth)acrylate content has been carried out taking into account several theories predicting the dependence of the glass transition temperature on the copolymers composition. The copolymers in which the molar fraction of methacrylic acid did not exceed ca. 65 mol % exhibit glass transition. Glass transition temperatures increase with the increase of molar fraction of methacrylic acid.
