Abstract
This invention relates to a stabilization composition, particularly adapted to prevent deterioration resulting from exposure to heat and light in polymeric materials, paints and dyes, consisting essentially of a normally liquid, branched chain dodecyl isomeric mixture of 2-(5'-dodecyl-2'-hydroxyphenyl)benzotriazole; to the method of preparing said stabilization composition and to the stabilized products having between about 0.05 and about 15 weight percent of said stabilization composition incorporated therein.
