Abstract
AbstractA theoretical investigation of the relationships between the photosensitivity of poly‐(vinyl cinnamate) and various factors—the degree of esterfication, the average molecular weight, and the concentration of sensitizers—was made under the assumption that the main response of the polymer to light is the production of crosslinking by the dimerization of cinnamoyl groups. The obtained equations are S = k16C2 for the degree of esterification, S = k22M̄ for the average molecular weight, and S = k33 (1 − e) + k34 for the concentration of sensitizers, where S is the photosensitivity of the polymer, C is the degree of esterification, M̄ is the average molecular weight, c is the concentration of sensitizers, and kij is a constant. It was shown that these equations agree well with the experimental data obtained by other authors.
