摘要：

Kinetic features of the photo- and thermo-chromic behaviour of new cholesteric triple copolymers with photosensitive spiropyran-containing side groups are considered. The kinetics of the back thermal process at different temperatures have been studied; activation energies for this process for the copolymers with different contents of the dye units have been obtained. The photochromic homopolymer and copolymers with a low content of dye units are shown to possess maximum values of the activation energy.
