Crystallization and thermal properties in waterborne polyurethane elastomers: Influence of mixed soft segment block
Popis výsledku v původním jazyce
A series of nontoxic biodegradable waterborne polyurethane (WBPUs) elastomers were synthesized by two-step polymerization, using isophorone diisocyanate (IPDI), 1,4-butandiol (BDO) and L-lysine as a chain extender and a range of soft segments with various macrodiols composition. The soft segment was formed by replacing polycaprolactone diol (PCL) as a polyester type polyol with hydrophilic polyether type polyol. Hydrophilic poly(ethylene glycol) (PEG) or poly(propylene glycol) (PPG) different block lengths were used to this purpose. Fourier-transformed infrared spectroscopy (FTIR) was used for evaluation of degree of phase separation. The effect of the soft segment composition on the thermal properties of polyurethane elastomeric films was investigatedby means of thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC). The thermal stability of materials is influenced by composition of soft segments and it was explained by the effect of oxygen content of polyether p
