Abstract : A process for preparing copolymers from N, N'disodium-N,N'-diacetyl-p-phenylene diamine and xylylene dichloride was established. Polymers that melt from 200 to 800 F and soluble in certain organic solvents were prepared. A polyimine was prepared from p-phenylene diamine and terephthalaldehyde which exhibits good thermal stability up to 800 F and is insoluble in organic-solvents. Hydrogenations were unsuccessful. Polymers were made from alpha,alpha'dichloro-p-xylene and diamines of various molecular structures. Polymers obtained with p-phenylene diamine were selected as the best candidate for investigation with thermal stability at approximately 500 F. Studies of crosslinking the polyamine with anhydrides and isocyanates were conducted. No significant improvement in properties over those of the pure resin was observed. Polyamines were found to be resistant to many chemicals and solvents. They are least resistant to mineral acids, being decomposed by both sulfuric and nitric acids. The electrical properties of polyamines and polyimines were found to be comparable to certain common commercial plastics. (Author)
