✦ Synopsis
The synthesis of comb-like polymers containing cinnamic acid derivatives in the side chains is described. The disappearance of thermal transitions after UV-irradiation of the polymer samples was demonstrated by DSC measurements in the case of the liquid-crystalline homopolymer poly(4-propoxyphenyl 4-(6-acryloyloxyhexyloxy)ci~amate] and the side-chain crystallizable copolymers poly[4-(6-acryloyloxyhexyloxy)cinnamic acid-co-hexadecyl acrylate). A significant influence of UV-irradiation on the permeation activation energy of 1 -butanol through polyamide composite membranes containing a fiim of the photosensible comb-like polymers was observed.
