Abstract:
An amino compound containing at least one primary amino group, a carbonyl compound containing at least one aldehyde or keto group and an isonitrile compound are applied to a cellulosic material and reacted thereon. The cellulosic material so modified has increased resistance to degradation from heat and acids and is suitable as an insulator in electrical devices.
