HIGH TEMPERATURE POLYAMINE RESINS.

Abstract

Several polyamine and polyimine type resins were prepared using condensation polymerization reactions. Molar ratios of reactants were varied to prepare resins with various degrees of solubility (for coating application) and moldability. The 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. From the standpoint of thermal stability, polyimines stable up to 700 F are superior to polyamines which show weight losses of 10 to 20% in 24 hours at 600 F. Polyimines are infusible and insoluble, and as such cannot be molded or cast into films. Polyamines, however, can be processed in both ways. Carborane and neocarborane were synthesized and infrared analyses characteristic of these materials were obtained. Derivatives of these materials which can be incorporated into polyamine resins were prepared. (Author)
