DEVELOPMENT OF METHOD FOR THE SYNTHESIS OF POLYURETHANES BRANCHED STRUCTURE CONTAINING ISOCYANURATE FRAGMENTS IN MACROCHAINS. STUDY THEIR STRUCTURE AND PROPERTIES
Journal Title: Вісник Одеського національного університету. Хімія - Year 2016, Vol 21, Issue 4
Abstract
Based polyoxypropylene glycol, TDI, isocyanurate HDT-90 and a chain extender – adipic acid dihydrazide (ADH) at different molar ratio of isocyanurate of TDI and polymeric materials synthesized new branched structure. The physico and mechanical properties of the material depending on the ratio of the isocyanate components. The introduction into the structure of polyurethane (PU) isocyanurate heterocyclic moieties of the matrix increases the tensile strength and decrease in elongation at break. The effect of the isocyanurate in the physical and mechanical properties of the new PU material, the dependence on the ratio of the starting components.
