摘要:A process for the production of an air-drying, modified amino- resin, whichprocess comprises co-polycondensing one or more dialkyl ether compounds, which aredialkyl ether of the dimethylol derivatives of compounds containing two primary amidogroups or similar groups, with at least one compound containing an auto-oxidative group,or polycondensing the said one or more dialkyl ether compounds and reacting thecompound containing an auto-oxidative group with the condensate; the alcohol releasedbeing removed from the mixture. The auto-oxidative groups are typically supplied byallyl ethers and the dialkyl ether compound is e.g. bismethoxymethylene urea. Themodified resins rapidly form hard films when exposed to atmospheric oxygen in thepresence of drying agents.
