Abstract
The preparation and characterizations of soluble copolymers poly (p-phenylene terephthamide-co-furandicarboxylic p-Phenylenediamine)(PPTA-co-PPF) by direct polycondensation was described. The chemical structure of polyamides was investigated by 1H NMR and FT-IR. The good solubility of copolymers in organic solvents was certified at room temperature. Their thermal stability and mechanical properties were observed by TGA and tensile testing and then compared with that of traditional high performance aromatic polyamides (PPTA and PMIA, for example, with trademarks of Kevlar® and Nomex®). The furan ring incorporated polyamide was expected to form thermal reversible cross-linked polymer network through D-A reaction.
