Abstract

This paper proposes a new method for the laboratory measurement of the shrinkage of UV-hardenable composites during polymerization. This method is used to investigate the shrinkage of UV-hardenable composites, as well as to study how the physical and chemical properties of polymers depend on the composition and ratio of the components in the composite. Recommendations are given for choosing the optimum formulations of composites for fabricating various optical elements based on them.
