摘　　要：合成了１， ３－二甲基－１， ３－二乙基－１， ３－双［３－（２， ３－环氧丙氧基）两基］二硅氧烷（ＴＥＤＳ）和 １， ３－二甲基－１， ３－二乙基－１， ３－二胺丙基二硅氧烷（ＴＡＤＳ）。用 ＦＴＩＲ和 ＤＳＣ对ＴＥＤＳ／ＴＡＤＳ体系的固化反应动力学进行了研究，结果表明：反应对ＴＥＤＳ和ＴＡＤＳ均为一级反应，固化体系的反应活化能在 ４５－６５ｋＪ／ｍｏｌ，与文献报道的双酚 Ａ环氧树脂的反应活化能相一致。1, 3-dimethyl-1, 3-diethyl, 1, 3-bis (3- (2, 3-epoxypropoxy) propyl ) disiloxane (TEDS) and l, 3-dimethyl-1, 3-diethyl-1, 3-bisaminopropyl disiloxane (TADS) were synthesized. The curing kinetics of TEDS/TADS system was studied by FTIR and DSC. First order kinetics was proposed for TEDS and TADS. The curing reaction energy was 45-65kJ/mol, which is in agreement with the value of biphenol A epoxy resin in literature.
