Abstract
Evolutive dissipative structures were observed during UV irradiation o f the surface of acrylate films leading to photopolymerization. Self-o rganization results in the formation of hexagonal or square cells, wav es, stars, and spots. These different situations were observed on the same polymer mixture. Thermodynamics of relief formation was applied t o these peculiar cases. Evidence was provided for the influence of sur face adsorption and bulk viscosity.
