Abstrak

The thermoplastic polyurethane elastomers based on oligo-glycidyl azide (oligo-GA) with oligo-(3,3-bis(azidomethyl)oxetane) (oligo-BAMO), oligo-(3-azidomethyl-3-methyloxetane) (oligo-AMMO) and oligo-(3-nitraminomethyl-3-methyloxetane) (oligo-MNAMMO) were synthesized. Thermoplastics were characterized using 1H and 13C NMR, IR spectroscopy, CHN elemental analysis and GPC techniques. Depending on the nature of initial oligomers, such as oligo-MNAMMO, oligo-AMMO, oligo-BAMO and oligo-GA, features of formation of supramolecular structures in segmented polyurethanes were studied. The results of X-ray diffraction analysis of the samples with crystalline segments were shown. Phase separation factors in the structure of thermoplastics were interpreted based on FTIR, DSC analysis and the solubility parameters of the initial polyethers.
