以二氨基磺酸盐配合物合成了一系列主链上合金属元素（Ｃａ，Ｎｉ，Ｃｏ，Ｃｕ）的聚脲聚合物．用ＩＲ和１ＨＮＭＲ对其结构进行了表征，以ＴＧ－ＤＴＡ研究了其热性能，并讨论了金属元素种类及其含量对聚脲聚合物溶液粘度的影响．
A series of polyurea polymers of alloying elements (Ca, Ni, Co, Cu) in the main chain were synthesized from bis sulfamate complexes. Their structures were characterized by IR and 1HNMR. Their thermal properties were investigated by TG-DTA. The effects of metal species and their contents on the viscosity of polyurea polymers were also discussed.
