摘要：
The influence of reactive dyes and their deactivated forms on the thermal degradation of polyvinylalcohol (PVA) and polycaproamide (PCA) fibers was investigated. Complex thermographic analysis in air and inert atmosphere showed that fibers dyed by reactive dyes are more resistant to thermo-oxidative degradation than untreated PVA and PCA fibers. A possible mechanism of the stabilizing influence of the dyes on the thermooxidative degradation of the investigated polymers was proposed.
