摘要: Fully aliphatic polyimides (APIs) have been synthesized. APIs were prepared by poly(addition-condensation) of the alicyclic dianhydride bicyclo[2.2.2]octane-2, 3, 5, 6-tetra-carboxylic 2, 3:5, 6-dianhydride with diamine 5-amino-1, 3-trimethylcyclo-hexanemethylamine, mixture 5- and 6-bis(aminomethyl)bicyclo[2.2.1]heptane or 1, 4-cyclohexanebis(methylamine) in m-cresol at high temperature. The polymerization proceeded smoothly 200 °C produced inherent viscosities up to 0.48 dl g−1. soluble a wide range polar solvents showed thermal stability excellent transparency.
