摘要
用溶液聚合法合成了四种聚氨酯、聚脲模型化合物.并用凝胶渗透色谱,应力—应变,广角X射线衍射等手段检验了在相界面或在硬段微区,不同键对聚合物分子量、力学性质和聚合物形态的影响.
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.
