Abstract
Abstract Pentaerythritol tetracinnamate (PTC) was obtained in several different crystalline forms, and its solid state photopolymerization induced by u.v. irradiation, was carried out under two different experimental conditions. The structure of one crystalline form (α-PTC), the X-ray diffraction pattern of the photopolymerization product and the i.r. spectra before, during and after the u.v. irradiation are given as experimental evidence for a possible two-step mechanism of the photoreaction. This mechanism implies that the crystal structure of the monomer controls topochemically the reaction at least in its first step.
