  • Patent number: 5795499
    Abstract: Polymers are stabilized against degradation by the addition of a liquid composition comprising an organic solvent and at least 40% by weight of a triaryl triazine of the formula (I): ##STR1## wherein X, Y, and Z are each the same or different aromatic carbocyclic radicals, and at least one of X, Y, and Z is substituted by a hydroxy group ortho to the point of attachment to the triazine ring, and at least one of R1 to R9 is an alkoxy radical of the formula, --O-(mixed alkyl) substituted at a point para to the point of attachment to the triazine ring, and the remainder of R1 to R9 are selected from the group consisting of hydrogen, hydroxy, alkyl, alkoxy, sulfonic, carboxy, halo, haloalkyl, and acylamino; with the proviso that --O-(mixed alkyl) is an alkoxy radical formed from an mixture of isomeric C.sub.6 to C.sub.12 alkyl halides containing at least 10% each of at least three different isomers.
