| Abstract: | Effect of urethane and urea linkages on the properties of polyurethane and polyurea solution polymer was investigated. These linear thermoplastic polymer was synthesized by a two -step solution polymerization method. GPC,Stress-Strain testing and WAXS were used to characterise the samples to evaluate the effectsondifferent linkages.either at the interface of the phase boundaries or within the hard segment domins.on the molecular weight,mechanical properties and morphology. |
