Abstract
The invention comprises compounds of formula <FORM:0996245/C2/1> wherein n is 1 or 2, R1, R2 and R3 are alkyl groups having a total of 3-23 carbon atoms, R4 is halogen, alkyl or alkoxy, x is 0-4 and the carboxyl groups are on non-adjacent carbon atoms. These compounds are made by reacting together the appropriate terephthalic, isophthalic or trimeric acid or their acid halides with a p-t-alkylphenol (or with an isomeric mixture of alkylphenols containing predominantly this isomer). A number of examples are provided in which the unsubstituted carboxylic acid chlorides are reacted with various phenols in presence of Mg, triethylamine or pyridine, and optionally benzene.ALSO:Polymers are stabilized against the effects of ultra-light by incorporating a compound of formula <FORM:0996245/C3/1> wherein n is 1 or 2, R1, R2 and R3 are alkyl groups having a total of 3-23 carbon atoms, R4 is halogen, alkyl or alkoxy, x is 0-4 and the carboxyl groups are on non-adjacent carbon atoms. The polymers may be derived from monomers having ethylenic unsaturation, or they may be cellulose derivatives (see Division B5), polyesters, epoxy resins, polyurethanes, phenolic resins, aminoplasts, polyamides, polyethers or polymeric aldehydes. Examples describe the stabilization of natural rubber film and chlorinated rubber, polyethylene, polypropylene, polystyrene, styrene-butadiene, styrene-acrylonitrile, ethylene-maleic anhydride, vinyl methyl ether-maleic anhydride, styrene-methyl methacrylate, poly(ethyl methacrylate), polyvinyl chloride, polyvinylidene chloride, vinyl chloride-vinylidene chloride; polymeric formaldehyde resin; and 1,5-pentanediol/sebacic acid/4,41-dicarboxydiphenylsulphone polyester.ALSO:Cotton, linen, regenerated cellulose, kapok, hemp, twines, wood-pulp, paper, cardboard and pressed board are stabilized against the effects of ultra-violet light by incorporating a compound of formula <FORM:0996245/D1-D2/1> wherein n is 1 or 2, R1, R2 and R3 are alkyl groups having a total of 3-23 carbon atoms, R4 is halogen, alkyl or alkoxy, x is 0-4 and the carboxyl groups are on or adjacent carbon atoms. In Example 3, a piece of filter paper is dipped in a 0.45% chloroform solution of [4 (1, 1, 3, 3-tetramethylbutyl) phenyl] 4-t-butylphenyl isophthalate and dried.
