摘要：

Radical thermally initiated homopolymerization of methacrylic monomers based on aurone has been studied. Photochemical properties of these methacrylic monomers by UV-visible spectroscopy were investigated. It is shown that the new compounds are capable to radical homopolymerization and photoinduced cis-trans isomerization. It was found that increasing the electron donation of the substituent accelerates the process of radical homopolymerization of monomers. It was found that increasing the electron acceptance of the substituent accelerates the process of cis-trans isomerization. The rate constants and half-transformation times of cis-trans photoisomerization were determined by the tangent of the slope of the dependence Ln(D-fss-D-0)/(D-fss-D-t) on the irradiation time of the solutions.
