| 内容記述 | Mechanical properties of polyurethane networks prepared by three different methods were studied. The polyurethanes were prepared from poly (oxypropylene) glycol, 2, 4 - tolylene diisocyanate, and I, 4 - butane diol. The used preparation methods were prepolymer method (P-series), one-shot method (O-series), and semi-polymer method (S-series). The networks obtained were characterized through measurements of allophanate concentration, density, swelling behavior in benzene, thermal properties by means of DSC, wide angle X-ray diffraction scattering, electron microscopy, stress-strain behaviors, and dynamic mechanical properties. Concentration of allophanate linkages in O-series polyurethanes was higher than that of S-, and T-series polyurethanes. Glass transition temperature of O-series polyurethanes was slightly higher than that of other series polyurethanes. X-ray diffraction patterns showed a diffuse amorphous halo for all series polyurethanes. Microgloblues were observed for P-, and S series polyurethanes with high hard segment contents. Young's moduli of P-, and S-series polyurethanes were higher than those of O-series polyurethanes. | |||||||||
