Fatty amines as curing agents of epoxy resins were intercalated into α-ZrP: 1,3 propanediamine（α-ZrP・PrDA）, 1,4 butanediamine（α-ZrP・BuDA）, and diethylenetriamine（α-ZrP・DETA）.The intercalated α-ZrP as thermal latent curing agents were examined with reaction of glycidylphenyl ether（GPE）. The conversion factor of GPE at 140℃ for 24 h, the conversions were 94％ for α-ZrP・BuDA and 89％ for α-ZrP・DETA. As the conversion of α-ZrP・PrDA was 47％. The conversionof α-ZrP・PrDA was lower than that of α-ZrP・BuDA and α-ZrP・DETA. The thermal stabilitiesat 40℃ for 15 days were tested. The reaction did not proceed in the presence of all intercalatedcompounds. α-ZrP・BuDA and α-ZrP・DETA were served as good thermal latent curing agents inthe reaction of GPE.
