Studies on new non‐shrinking, thermally stable araldite‐type photopolymers with pendent aryl acryloyl‐groups. II. Photoreaction of some arylacrylic‐acid methyl esters in the liquid state

Abstract

AbstractLiquid aryl acrylic acid methyl esters, e.g. furan acrylic acid methyl ester and thienyl acrylic acid methyl ester, were UV‐irradiated (λ ≥ 280 nm) at a temperature of 2°C above their melting points. IR‐methods were used in order to monitor the photoreactions which are of a second order kinetics. The application of GC‐MS indicated that dimers, trimers and tetramers, but no polymers were formed under the chosen conditions.
