Synthesis and Properties of Polyimides and Copolyimides Containing Pyridine Units: A Review
Author(s):
Abstract:
Agreat number of studies of new polymer syntheses have been focused on the preparation of high-performance polymers. Imide polymers and their copolymers are a well-established class of high-performance polymers that show good combination of mechanical, electrical, and thermal properties. This paper reviews the synthesis and properties of polyimides and copolyimides with different structures specially those containing pyridine ring in their structure. Advantages of using a pyridine nucleus is relayed on two factors. First, high thermal stability derived from its molecular symmetry and aromaticity, and second, improved solubility of the pyridine (in respect to phenyl group) containing polymers because of increased dipoledipole interactions of polymer-solvent system. This discussion covers different structures of pyridine-based polyimides and their physical and thermal properties. The subtle variations in the structure of the monomers have a great effect on the properties of the final polyimides. Various structural features that are important for understanding the structure/property relationships have been discussed.
