Abstract
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): 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 C₆ to C₁₂ alkyl halides containing at least 10% each of at least three different isomers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
91 words
A process for preparing a triaryl triazine ultraviolet light absorber by alkylating with mixed isomeric alkyl halide reactant a triaryl triazine reactant represented by the formula (II) below: wherein X, Y, and Z are each the same or different aromatic carbocyclic radicals, and at least one of X, Y, and Z has two hydroxy groups having positions respectively, ortho and para to the point of attachment to the triazine ring, and the remainder of R10 to R18 are independently selected from hydrogen, hydroxy, alkyl, alkoxy, sulfonic, carboxy, halo, haloalkyl, and acylamino.
Claim 2
Dependent Claim
42 words
The process of Claim 1 wherein the triaryl triazine reactant is represented by formula (III) below: wherein R19, R10, R21, R22, R23, R24, and R25 are independently selected from the group consisting of hydrogen and one to twelve carbon atom alkyl groups.
Claim 3
Dependent Claim
18 words
The process of claim 1 wherein the mixed isomeric alkyl halide reactant is a mixed isomeric alkyl chloride.
Claim 4
Dependent Claim
21 words
The process of Claim 1 wherein the alkyl group of the mixed isomeric alkyl halide is derived from "Oxo" process alcohols.
Claim 5
Dependent Claim
138 words
A triaryl triazine ultraviolet light absorber represented by the formula (I) below: 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 C6 to C12 alkyl halides containing at least 10% each of at least three different isomers.
Claim 6
Dependent Claim

The triaryl triazine ultraviolet light absorber of claim 5 wherein; (a) X, Y, and Z are each phenyl groups, (b) only one of X, Y, and Z is substituted by a hydroxy group ortho to the point of attachment to the triazine ring, (c) at least one -O-(mixed alkyl) radical is substituted on the same phenyl radical as the hydroxyl group at a point para to the point of attachment of the phenyl radical to the triazine ring, and (d) the remainder of R1, R2, R3, R4, R5, R6, R7, R8, and R9 are selected from the group consisting of hydrogen and alkyl groups.
Claim 7
Dependent Claim
27 words
The triaryl triazine ultraviolet light absorber of claim 5 wherein said -O-(mixed alkyl) radical is derived from a mixed isomeric alkyl halide derived from "Oxo" process alcohols.
Claim 8
Dependent Claim
