Abstract:
Solid aromatic polymers, such as branched polyphenylenes, are reacted with a reactive gas such as a NO. sub. 2 -N. sub. 2 O. sub. 4 mixture, chlorine and sulfur trioxide without solvent or catalyst. The extent of reaction depends on reaction time and temperature and on the concentration of the reactive gas.
Branched Nitropolyphenylenes And Compositions Therefrom
Branched nitropolyphenylene resins are disclosed which have a substantial degree of branching. Also disclosed is a polyphenylene resin mixture comprising branched nitropolyphenylenes and branched soluble polyphenylenes. This resin mixture is used to prepare asbestos, glass, carbon and graphite fiber composites.
