摘要
用油酸改性后的多胺与环氧树脂预聚物得到粘度低，吸水量小，添加量范围大，室温胶凝时间长的新型环氧树脂因化剂。
The polpethenepolymine was reacted with oleic acid at 150～170℃ for 8hr.and then with epoxy resin at 140℃ to obtainthe prepolymer as cure agent for eproxy resin.The structure was characterized by IR.The prepolymer is of low hygroscapicity,low vicosity and wide addition capacity and long active time at room temperature.
