摘要
用溶液聚合法合成了五种不同扩链剂的聚氨酯,用凝胶渗透色谱,差热分析,动态力学温度谱,广角X射线衍射等手段,讨论了不同扩链剂对聚合物分子量,动态力学性质,热性质,力学性质和聚合物形态的影响.
A series of polyurethanes with various chain extender were synthesized vis solution polymerization. GPC,DSC,DMS,Stress-Strain testing and WAXS were used to characterize the samples to evaluate the various chain extender effects on molecular weight,properties of dynamic mechanical .thermal .mechanical,and morphology.
