Аннотация

The peculiarities of how hardener influences the structural, physicochemical, dynamic elastic hysteresis, and relaxation properties of materials based on oligodienediol Krasol LBH-3000 are established. It is shown that polydieneurethanes hardened under conditions where the ratio of the reactive groups is NCO/Σ(OH) ≈ 0.9−1.25 mol/mol have optimal properties.
