摘要： Uri等曾对水杨酸铬系列金属螯合物催化环氧树脂与羧酸之间的固化反应进行了研究,但对呋喃甲酸铬系列金属整合物催化环氧树脂与酸酐之间的固化反应的研究,尚未见报道.

Abstract: The catalytic reactivities were studied for the curing of epoxy resin E-51/methylated te-trahydro-o-phthalic anhydride (MTHPA) catalyzed by Cr(Ⅲ) chelates. It is indicated that the most active catalysts are the Cr(Ⅲ) chelates of 5-tertiary butyl furan-methanoic acid, 5-isopropyl furan metharsoic acid and 2-ethyl-hexanoic acid. The effect of various ligands on the reactivities of the Cr(Ⅲ) chelates is discussed. The curing course of the reactions of E-51/MTHPA catalyzed by Cr (Ⅲ) chelates were also studied.
