Abstract 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)cinnamate] 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 membrance containing a film of the photosensible comb‐like polymers was observed.
