Cocarbinization of Blends of Polyacrylonitrile with Chitin and Chitosan

Abstract

The possibility of thermochemical cocarbonization of polyacrylonitrile with chitin and chitosan by combined heat treatment of their blends was examined. It was concluded that the components form complexes in dimethylformamide and dimethylacetamide at the temperature of polyacrylonitrile cyclization (230 3300oC). The main thermal characteristics and the coke numbers of the cocarbonization products were determined.
