OPTIMECHANICAL PROPERTIES OF DENSELY CROS S-LINKED POLYMERS ON THE BASIS OF DIALLYL AND DIVINYL MONOMERS

Optimechanical properties of densely cross-linked polymers on the basi s of diallyl and divinyl monomers were studied. It was shown that the properties are determined by the topology of the network. The topology , in tum, depends on the structure of the monomers. A method of dividi ng the elasticity of strained polymers into energy and entropy compone nts was proposed that is based on the analysis of the linear temperatu re dependence of the elastic modulus on cooling of the polymer under a load. Such a division permits one to compare elasticities of densely cross-linked systems using a single parameter, i.e., the conventional number of chains in a unit volume.
