Chemical transformations during heating resols and resites containing carbonate

Chemical transformations were studied during heating resols containing carborane and corresponding resites. It was found that in the temperature range of 50–200° structure formation of oligomers containing carborane takes place by a mechanism which is conventional for resols. At temperatures higher...

Description
Summary:Chemical transformations were studied during heating resols containing carborane and corresponding resites. It was found that in the temperature range of 50–200° structure formation of oligomers containing carborane takes place by a mechanism which is conventional for resols. At temperatures higher than 200° significant chemical transformations take place of carborate groups of resites, the degree of transformations depending on conditions of heating (air, vacuum). It was shown that the most considerable differences in thermal stability of conventional phenol-formal-hyde and carborane-containing resites are observed under conditions of thermal oxidizing breakdown. Thermal oxidizing breakdown of several model compounds was studied.
