The physical-mechanical and dynamic properties of olygodiurethanes with different structure of networks

, , , , , ,

Abstract:

The main features of the influence of hardener on the structure, physico-mechanical, dynamic-elastic hysteresis and relaxation properties of materials based on oligodiendiol PDI-1K have been investigated. It is shown that the optimal level of the complex properties have polidienuretane, cured with a ratio of reacting groups NCO/S(OH) ~ 1,25-1,5 (mol / mol).
