| titleOfInvention | Film-forming copolymers |
| abstract | The invention comprises a film-forming copolymer of (a) at least one vinyl compound, (b) at least one maleic acid half ester and (c) at least one maleic acid half-amide, the amount of (a) being equal to 50-70 mol per cent and the sum of (b) and (c) being equal to 30-50 mol. per cent. The copolymer may be obtained by copolymerizing a vinyl compound with a mixture of at least one maleic acid half-ester and at least one maleic acid half-amide, or by copolymerizing a vinyl compound with maleic anhydride and then reacting the copolymer with at least one alcohol and at least one amine. The vinyl compounds may be styrene (which is the compound used in all the specific examples), alpha-methylstyrene, vinyl toluene, halogenated styrenes, vinyl acetate, vinyl propionate, vinyl chloride, vinyl sulphonic acid, vinyl phosphoric acid, vinyl ethyl ether, vinyl butyl ether, vinyl cyclohexyl ether, acrylic acid esters of alkyl or cycloalkyl alcohols containing 1-8 carbon atoms in the alcohol component, or acrylonitrile. The alcohols may have up to 15 carbon atoms and may be methanol, ethanol, propanol, butanol, isobutanol, ethylhexanol, cyclohexanol, or benzyl alcohol. The amines may have up to 16 carbon atoms and may be dibutylamine, di-isobutylamine, diethylamine, dipropylamine, cyclic hexamethylene imine, pyrrolidine or piperidine. Copolymerization may be effected in bulk, in suspension, or in solution in benzene, toluene, xylene or ethanol. As polymerization catalysts there may be used azoisobutyronitrile, hydrogen peroxide, benzoyl peroxide or alkali persulphates. The resulting lacquer resins are compatible with shellac or manila resins. |
