Abstract:<\/p>\n

Using the methods of dynamic mechanical analysis (DMA) and IR-spectroscopy, it has been studied the kinetics of curing and viscoelasticity properties of epoxyurethane network obtained by epoxydian resin and bifunctional oligocyclocarbonates (OCC). It was investigated the dependence of the glass transition temperature and the modulus of elasticity from the amount of entered cyclocarbonate. It was shown that at certain oligomers ratio it occured microheterogeneous division in the system. It was possible to determine features of the system formation and compare the relative abundance of functional groups of the oligomers in analysis of the epoxyurethane sol fraction. Aliphatic OCC modification of epoxy polymer improves its mechanical properties.<\/em><\/p>\n
