Abstract

A series of polyhydroxyamide copolymers (Co-PHAs) containing 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane (BAHHFP) and/or bis(3-amino-4-hydroxyphenyl) sulfone (BAHS) were synthesized via a low-temperature solution polymerization method. The synthesized Co-PHAs were characterized by Fourier transform infrared (FT-IR) spectroscopy, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). All the Co-PHAs were found to be soluble in organic solvents with or without LiCl. The chemical structures of the Co-PHAs were identified using FT-IR spectroscopic analysis. The DSC and TGA results showed that the inclusion of BAHHFP and/or BAHS in the Co-PHAs reduced the thermal cyclization temperatures as compared to DHB, which is due to the difference in the rotational energy of the diamine monomers.
