Features of formation and viscoelastic properties of epoxyurethanes based on aliphatic cyclocarbonate oligomers

By the methods of dynamic mechanical analysis (DMA) and IR spectroscopy, the kinetics of curing and viscoelastic properties of epoxy urethanes of network structure based on epoxy diane resin and bifunctional oligocyclocarbonates (OCCs) are studied. The dependence of glass transition temperature and...

Summary:By the methods of dynamic mechanical analysis (DMA) and IR spectroscopy, the kinetics of curing and viscoelastic properties of epoxy urethanes of network structure based on epoxy diane resin and bifunctional oligocyclocarbonates (OCCs) are studied. The dependence of glass transition temperature and gel fraction of the obtained polymer on the amount of injected cyclocarbonate is established. It is shown that modification of epoxy diane oligomer by aliphatic OCCs results in an increase in its mechanical properties, particularly cohesive strength.
