| 摘 要： | 以低分子聚酯多元醇与二异氰酸酯合成新型聚氨酯固化剂,分别研究了甲苯二异氰酸酯（TD I）、二苯基甲烷二异氰酸酯（MD I）与低分子聚酯多元醇的反应动力学。结果表明,TD I封端低分子聚酯多元醇的反应为二级反应,反应活化能为51.7 kJ/mol;MD I封端低分子聚酯多元醇的反应在反应温度低于70℃时也为二级反应,反应活化能为27.6 kJ/mol。

| Abstract: | The novel polyurethane curing agent was synthesized by low molecular weight polyester polyol and diisoeyanate. The reaction kinetics of TDI or MDI with low molecular weight polyester polyol were studied separately. The results showed that, the end capping reaction of TDI forminated low molecular weight polyester polyol was found to be reaction of second order and the activation energy was 51.7 kJ·mol^-1. The reaction of MDI forminated low molecular weight polyester polyol was also second order of reaction when the reaction temperature was below 70℃, the activation energy was 27.6 kJ-mol^-1. |
