Laws of Solid-Phase Thermochemical Transformations During Thermal Oxidation of m-,p-Aramid–Polyacrylonitrile Fibous Composites in the Presence of Pyrolytic Additives

Resumo

Thermochemical conversion of m-,p-aramid–polyacrylonitrile fibrous composites was investigated in the presence of small amounts of phosphorous compounds. Processes of polymer thermal transformation were characterized by thermogravimetry and oxygen index data. The basic laws of thermo-chemical transformations of the m-,p-aramid–polyacrylonitrile fibrous composites and their components in the presence of phosphorus compounds were determined. The most effective additives that achieve oxygen index value of 50% were determined.
