Random copolyimides with different proportions of a diamine component were prepared by polymerizing different compositions of diamines with various dianhydrides and imidized thermally to 260ยฐC. The imidization percent of poly(amic acid) was characterized at various temperatures by infrared spectrosc
## Abstract Soluble and stable precursors of aromatic imidodiamines were prepared and employed in polymerization reactions with aromatic dianhydrides to yield poly(amic acid ester)s. Thermal imidization of the polymers produced strictly aromatic copolyimides. The reaction of pyromellitic dianhydrid
