Patent ID: 6881772

Claim:
A composition comprising polypropylene and a light stabilizer mixture containing (A) 0.05 to 1% by weight, relative to the weight of the polypropylene, of a sterically hindered amine compound selected from the group consisting of the compounds 13, 14, 36-a, 36-b, 36-d, (81), (84-1), 96-I, 96-II, the product 100-A, 101-I, 105 and 106 (36-a) 1,2,3,4-tetrakis{2,2,6,6-tetramethylpiperidin-4-yloxycarbonyl}butane, (36-b) 1,2,3,4-tetrakis{1,2,2,6,6-pentamethylpiperidin-4-yloxycarbonyl}butane, with m 16 and m 16 being a number from 2 to 50; a product (100-A) obtained by reacting an intermediate product, obtained by reaction of a polyamine of the formula (100a-I) with cyanuric chloride, with a compound of the formula (100b-I), (B) 0.02 to 0.5% by weight, relative to the weight of the polypropylene, of CaO and (C) 0.05 to 0.5% by weight, relative to the weight of the polypropylene, of an aliphatic zinc or magnesium monocarboxylate having 1 to 24 carbon atoms.
