Features of thermochemical transformations during oxidation of m-,p-aramid–polyacrylonitrile fibrous composites

Fibre Chemistry Aims and scope

Thermal oxidation of m-,p-aramid − polyacrylonitrile polymer fibrous composites and their components was studied by instrumental analytical methods. It was found that mainly polyacrylonitrile fibre underwent chemical and structural transformations under the thermal oxidation conditions. Incorporation of up to 60% of it into a spinning mixture increased the oxygen index to the level of a thermally stable material (37%).
