ABSTRACT

The reaction of glycidyl phenyl ether (GPE) with 1-aminoalkanes-intercalated α-zirconium phosphate (α-ZrP·1-aminoalkane): 1-aminoalkanes 1-aminopropane (α-ZrP·Pr), 1-aminobutane (α-ZrP·Bu), 1-aminooctane (α-ZrP·Oct), and 1-aminohexadecane (α-ZrP·Hed) was carried out at varying temperatures for 1 h periods. Reaction progress was not observed until the reactants were heated to 80 °C or above. On increasing the temperature, the conversion factors increased such that, at 140 °C, conversions of 62% (α-ZrP·Pr), 60% (α-ZrP·Bu), 67% (α-ZrP·Oct), and 64% (α-ZrP·Hed) were obtained. The thermal stabilities as latent initiators were tested: GPEs reacted with α-ZrP·Pr, α-ZrP·Bu, and α-ZrP·Oct at 40 °C for 360 h achieved conversions of 83, 55, and 59%, respectively. In contrast, the reaction in the presence of α-ZrP·Hed did not proceed at 40 °C. The order of the thermal stability of GPE in the presence of α-ZrP·1-aminoalkane intercalation compounds was: α-ZrP·Hed > α-ZrP·Bu ≈ α-ZrP·Oct > α-ZrP·Pr. © 2014 Wiley Periodicals, Inc. J. Polym.
