Coating material of polymers and salts of fatty acids

Claim 1

Powder coating material for glass which consists essentially of a copolymer of α-olefins of the formula R--CH=CH 2 , where R is a radical selected from the class consisting of hydrogen and alkyl radicals having from 1 to 8 carbon atoms, and α,β-ethylenically unsaturated carboxylic acids having from 3 to 8 carbon atoms, said copolymer having from 0% to 90% of the carboxylic acid groups ionized by neutralization with uncomplexed metal ions, said metal ions having an ionized valence of from one to three inclusive when the unsaturated acid is a monocarboxylic acid and an ionized valence of one when the unsaturated acid is a dicarboxylic acid said copolymer being a copolymer of the α-olefins and the unsaturated carboxylic acid in which the carboxylic acid groups are randomly distributed over all molecules and in which 1 the α-olefin content of the copolymer is at least 50 mol percent, based on the α-olefin-acid copolymer, 2 the unsaturated carboxylic acid content of the copolymer is from 0.2 to 25 mol percent, based on the α-olefin-acid copolymer, and 3 any other monomer component optionally copolymerized in said copolymer is monoethylenically unsaturated, and 1 to 20% by weight, based on the weight of the copolymer, of an additive selected from the class consisting of monobasic fatty acids of 10 to 22 carbon atoms, metal salts of monobasic fatty acids of 10 to 22 carbon atoms, and mixtures thereof.
