The latent catalytic abilities of tertiary amines-intercalated α-zirconium phosphate [(α-ZrP·amine): 1,4-diazabicyclo[2,2,2]octane (α-ZrP·DABCO) and 1,8-diazabicyclo[5,4,0]undec-7-ene (α-ZrP·DBU)] were examined by copolymerization of glycidyl phenyl ether (GPE) and hexahydro-4-methylphthalic anhydride (MHHPA) at varying temperatures for 1 h periods. Polymerization was not observed until the reactants were heated to 100 °C or above. Upon increasing the temperature, the conversion factors of GPE increased such that, at 140 °C, both conversions were over 90% for α-ZrP·DABCO and α-ZrP·DBU. The thermal stabilities of GPE and MHHPA with the catalysts at 40 °C for 144 h were tested: GPE with α-ZrP·DBU achieved conversions of 9%. The reaction in the presence of α-ZrP·DABCO did not proceed at 40 °C for 144 h.

DABCO和DBU插入的α-磷酸锆在缩水甘油基苯基醚（GPE）和六氢-4-甲基邻苯二甲酸酐（MHHPA）的共聚中作为潜在的热催化剂

叔胺插层的α-磷酸锆[（α-ZrP·胺）：1,4-二氮杂双环[2,2,2]辛烷（α-ZrP·DABCO）和1,8-二氮杂双环[5]的潜在催化能力通过缩水甘油基苯基醚（GPE）和六氢-4-甲基邻苯二甲酸酐（MHHPA）在1 h的时间内共聚，研究了[4,0]十一碳-7-烯（α-ZrP·DBU）]。直到将反应物加热至100℃以上才观察到聚合。随着温度的升高，GPE的转化率增加，以至于在140°C时，α-ZrP·DABCO和α-ZrP·DBU的转化率均超过90％。测试了GPE和MHHPA在40°C催化剂下144 h的热稳定性：具有α-ZrP·DBU的GPE的转化率为9％。在存在α-ZrP·DABCO的情况下，该反应在40°C下未进行144小时。
