Abstract
A method of increasing the oxygen index (OI) of polyoxadiazole fibers by introducing fire retardant nano(micro)-additives into the polymer before the fiber formation is presented. The following additives are studied: dicarboxydiphenyl oxide, brominated and chlorinated phthalocianines, and carbon black. The use of these additives in the amount of 2–5% of the polymer weight in spinning solutions makes it possible to produce fibers with OI of up to 34 % and thermal stability of up to 84%.
