DOI: dx.doi.org/10.14314/polimery.2003.171


Summary

A review of methods of asynthesis of industrially manufactured polyimides (PI) has been done. Two-step method based on the suitable polyamide acid (PAA) preparation and its imidization to PI as well as one-step method consisting in direct polycondensation of aromatic tetracarboxylic acids' di-anhydrides with aromatic diamines were described. PAA physicochemical properties (especially hydrolysis ability) and imidization mechanism were discussed. The effect of chemical structure of PI discussed on the conformation of their macromolecules as well as on some mechanical and thermal properties has been characterized. Basic information concerning polyetherimides, polyamideimides, fluorinated PI and poly(bismaleateimides) were also given in the review.


Keywords: aromatic polyimides, polyetherimides, polyamideimides, fluorinated polyimides, poly(bismaleateimides), synthesis, properties
