Biobased furano-pyridinic copolyamide-imides preparation, characterization and degradation study

Abstract

Novel copolyamide-imides containing furan moieties were prepared from the resulting furanic dihydrazides and pyridinic dihydrazides monomers with various aromatic dianhydrides. Their copolymers were prepared by applying a one sept melt polycondensation method at high temperature. The inherent viscosities of these copolymers are in the range 0.024–0.064 L/g. The copolyimide-imides furano-pyridinic are amorphous with Tg ranging from 95 to 152 °C and their thermal and hydrolysis stabilities are influenced by the presence of the pyridinic function. These copolymers having a good stability in the H₂O₂/CoCl₂ medium.
