More Information
Summary:A stabilization mixture is described for use with polymeric materials, the mixture evidencing high stabilization efficiency against the effect of ultraviolet radiation which being of low toxicity. The mixture comprises from 80-100%, by weight, of a mixture of 2,2,6,6-tetramethyl-4-piperidinol esters and from 0-20%, by weight, of the ammonium carboxylates thereof. The mixture is prepared by heating derivatives of 2,2,6,6-tetramethyl-4-piperidinol with mixtures of stearic, palmitic, heptadecanic, myristic and oleic acids at temperatures ranging from 150-260 degrees C.
