BLOCKED-DIISOCYANATE-BASE SHOCK-RESISTANT POLYURETHANE AND METHOD OF ITS SYNTHESIS Russian patent published in 2002 - IPC

Abstract RU 2194724 C2

FIELD: polyurethane materials. SUBSTANCE: invention describes method of synthesis of shock-resistant modified polyurethane based on adduct of bisphenol A diglycidyl ester with hydroxyl-containing monoamine and diisocyanate blocked with ε-caprolactam taken in the mole ratio = (1-2):1, respectively, and method of its synthesis also. Invention provides synthesis of shock-resistant polyurethane showing 4-6-fold more energy of viscous destruction as compared with epoxy-amine polymers by variation of ratio of functional groups and amount of modifying additions. EFFECT: improved method of synthesis and properties of polyurethane. 3 cl, 3 tbl, 16 ex
