Abstract:
A procedure for synthesizing an open‐chain polyimide has been developed. O ‐Substituted hydroxylamines were found to behave as difunctional nucleophiles in acylation under appropriate conditions, and thus the reaction of equimolar amounts of benzyloxyamine and terephthaloyl chloride gave rise to the corresponding novel type of polyimide, an open‐chain polyimide. The results of polymerization under various conditions indicated the reaction to proceed efficiently in N , N ‐dimethylacetamide in the presence of an acid acceptor system composed of double the molar quantity of triethylamine and the molar quantity of pyridine to give the polyimide with a high molecular weight. In contrast to the conventional polyimides having cyclic imide structures, the resulting open‐chain polyimide exhibited remarkable solubility in common organic solvents and a low glass transition temperature.
