Cured linear hybrid epoxy-amine hydroxyurethane-grafted polymer are preparedby novel structure with lengthy epoxy-amine chains, pendulous hydroxyurethane units and a controlled number of cross-links. These hybrid polymers combine increased flexibility with well balanced physical-mechanical and physical-chemical properties of conventional epoxy-amine systems and may be used, for example, for manufacturing of synthetic/artificial leather and sport monolithic floorings. US Patent Application 14/296,478, filed June 05, 2014.

Keywords: linear epoxy-amine chains, hybrid hydroxyurethane-grafted polymers, synthetic nonisocyanate leather.

In a classical ferroelectric material the real condition of the crystals, caused different type defects, leads to insignificant effects of degradation. In systems of firm solutions and difficult oxides эфти effects are the integral physical properties. The features of degradation of phase transitions are available and in a ferroelectric material-relaksorakh.

Keywords: Phase transitions, ferroelectric material, perovskites, difficult oxides, ferroelectric material-relaksory
