Mixture of substances comprises a salt of metal cations and thermally activatable reducing anions, and at least one polyol, where the thermally activated reducing anions are anions, during reaction at a temperature between 100-450[deg] C, having a normal potential value of less than 0 V with a sufficient reaction rate at 25[deg] C relative to the standard hydrogen electrode, the reaction rate of the reaction of the thermally activatable anion is at least 10 mol.% for a period of one hour, and the anion is an organic molecule having at least two hydroxy groups per molecule in the polyol to be used. Independent claims are included for: (1) thermoplastic molding compounds, comprising the mixture of substances; (2) producing the thermoplastic molding compounds, comprising blending, mixing, kneading, compounding, extrusion or rolling (i) 10-99.75 wt.% of thermoplastic polymer(s), (ii) 0.05-10 wt.% of the salts of metal cations and the thermally activatable reducing anions, (iii) 0.1-10 wt.% of the polyols, and (iv) 0.1-70 wt.% of other ingredients, at a temperature of 220-400[deg] C; (3) fibers, films or molded articles obtained by injection molding, extrusion, or blow molding of the thermoplastic molding compounds; and (4) reducing photo-oxidative and/or thermo-oxidative damage of thermoplastic molding compounds containing the thermoplastic polymer, or films, fibers or molded articles to be produced, comprising adding the mixture of substances to the thermoplastic polymer. |
