Abstract

New LINEAR POLYURETHANES (PUs) derived from bisl4 (6-hydroxynexoxy)phenyl)ether (HHPE) and tolylene diisocyanate were synthesized by melt step growth or solution polymerization . In conducting the process of polyadditon in solution at 80-90° C for about 4 h, NN-di-methylformamide as aprotic solvent, 1 wt % conc. of dibulyltin dilaurate as catalyst and -25 wt % conc. of monomers were used. We found rli, molecular weight (by GPC), and melting temperature for the reaction products. Thermal properties of the polymers were investigated by means of thermal gravimetric analysis and differential scanning calorimetry . The structure of the resulting products was confirmed by elemental analysis, Fourier transform infrared spectroscopy and X-ray diffraclometry. Segmented PUs were synthesized from variable amount of polytetramethylene oxide, tolylene diisocyanate and HHPE as chain extender in conditions established earlier for non-segmented PUs.
