Abstract
1,225,627. Polyurethane compositions. IMPERIAL CHEMICAL INDUSTRIES Ltd. 26 July, 1968 [31 July, 1967; 24 June, 1968], Nos. 35014/67 and 30004/68. Heading C3R. Non-foamed polyurethanes have present therein a sufficiency of a nickel salt of an acid of formula wherein R represents hydrogen or an aliphatic or homocyclic radical and R<SP>1</SP> represents an aliphatic of homocyclic radical or R and R<SP>1</SP> together form an aliphatic radical making, with the nitrogen atom, a non-aromatic heterocyclic ring, to provide a resistance to degradation by light. The polyurethanes are suitably those based on polyesters and, especially, polyethers and the amount of stabilizer used is preferably at least 0À15% by weight of the polyester or polyether. It is preferred to add the stabilizer to the reaction mixture when forming the polyurethane. Fillers may be added to the reaction mixture, as well as conventional catalysts for the NCO/OH reaction. In examples, the nickel salts used are nickel bis(N,N - dibutyl dithiocarbamate), nickel di(3,5 - di - tert - butyl - 4- hydroxybenzyl)dithiocarbamate and nickel methyl(3,5 - di - tert-butyl - 4 - hydroxybenzyl)- dithiocarbamate.
