Thermal Stabilization of Polycaproamide Composites Containing Flame Retardants

It was found that the degree of polymerization in heating PCA containing 10% TS-1 thermostabilizer varies to a smaller degree than for the initial polymer and polymer containing Stabilin. This is confirmed by the results of determining the content of terminal amino groups and melt flow index after prolonged heating of the composites. The effect of the thermostabilizers on thermooxidative degradation of PCA composites containing aminotrismethylenephosphonic acid ammonium salt as flame retardant was studied. It was shown that incorporation of TS-1 together with AMP AS to PCA increases the thermal stability of the composites. TS-1 stabilizer is recommended for treatment of PCA in the presence of flame retardants to obtain a polymer with high performance properties.
