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.

Abstract: Diureas are modified by heating until the molecular weight, calculated from the amount of ammonia liberated in the formation of biuret groups, has increased by at least 10% and are then reacted with formaldehyde and a monohydric aliphatic alcohol. The diureas are of the general formula H2N.CO.NH.R.NH.CO.NH2 where R is a divalent hydrocarbon radical, or a divalent aliphatic radical which contains one or two isolated nitrogen atoms in the chain. Solvents such as hydrocarbons and the ethers, half-ethers, esters and half-esters of glycols may be present during the condensation with the aldehyde and alcohol as may acid catalysts and modifying agents such as urea, thiourea, melamine or diaminotriazines. The solutions of the condensation products obtained may be used as varnishes, in conjunction with the usual hardening agents (e.g. alcoholic hydrochloric acid) and pigments such as rutile.
