Ethylenediaminetetraacetic acid dianhydride (EDTADA) is a six-membered cyclic anhydride that contains two tertiary amino groups in the structure. In this work, we have demonstrated that a curing reaction of diglycidyl ether of bisphenol A (DGEBA) and EDTADA proceeded efficiently without any accelerant such as tertiary amine and imidazole. This result proves that EDTADA can act as a self-sustaining accelerant for the curing reaction of the epoxy monomers. On the other hand, the curing reaction of glycidol with EDTADA proceed successfully via an initiation step owing to the esterification of primary alcohol and anhydride moieties. In this case, we demonstrate that EDTADA also works as an amine catalyst for esterification. Moreover, we have studied the adhesive properties of two types of epoxy resin derived from DGEBA and glycidol with EDTADA.

环氧单体与乙二胺四乙酸二酐的固化行为及性能

乙二胺四乙酸二酐 (EDTADA) 是一种六元环酐,其结构中含有两个叔氨基。在这项工作中,我们证明了双酚 A 的二缩水甘油醚 (DGEBA) 和 EDTADA 的固化反应在没有任何促进剂(如叔胺和咪唑)的情况下有效进行。该结果证明 EDTADA 可以作为环氧单体固化反应的自持促进剂。另一方面,由于伯醇和酸酐部分的酯化,缩水甘油与 EDTADA 的固化反应通过引发步骤成功进行。在这种情况下,我们证明 EDTADA 也可作为酯化的胺催化剂。此外,我们研究了两种衍生自 DGEBA 和缩水甘油的环氧树脂与 EDTADA 的粘合性能。
