Abstract
The use of asymmetric oxalic acid diarylamides of formula:- (in which R1 and R2 are C1-18 alkyl gps. opt. substd. with Cl, -OH, C1-4 alkoxy gps., -CO2H gps., -CN gps., carboxylic amides or C1-12 alkyl carboxylates, or by C3-4 alkenyl gpds., (Cl/OH-substd.) benzyl gps. an acyl gp. of up to 18C or by (Cl /C1-4 alkyl-substd.) benzoyl gp., R3 and R4 are C1-12 alkyl gps., a halogen, alkyl halide, -SO3H, ph- or C1-4 alkylphenyl or R3 and/or R4 form a condensed 6-membered atom. ring, m and n are 1 or 2, p and q are 1-3 with proviso that each of the ring systems bound via the -NH have not more than three substituents, that the sum m + (n-1) is 1 or 2 and that the substituents are such as so make (I) asymmetric) as UV stabilisers for poly(alpha-alkenes), PVC or mixts. of unsatd. polyesters with polymerisable vinyl monomers in amt. 0.01-10 wt.%.
