Abstract

Urea and a saturated non-hydroxylated aliphatic aldehyde other than formaldehyde are condensed in the presence of a monohydric alcohol, in the absence of strongly acidic or basic catalysts or added water, and at a temperature above 50 DEG C. but insufficient to cause any substantial insolubilization of the product. The term urea includes substituted ureas such as compounds of the general type <FORM:0494700/IV/1> wherein R1 and R3 may be hydrogen; alkyl, e.g., methyl, propyl or dodecyl; aralkyl, e.g. benzyl; aryl, e.g. phenyl or naphthyl; cycloalkyl, e.g. cyclohexyl; and wherein R2 may be oxygen or sulphur. Suitable aldehydes include acetaldehyde, propionaldehyde, isobutyraldehyde, heptaldehyde, butyraldehyde and nonaldehyde; suitable alcohols include ethanol, propanol, dodecanol, di-isopropyl alcohol, cyclohexanol, butanol, ethylene glycol monomethyl or monoethyl ether. The products may be blended with polyhydric alcohol-polybasic acid condensation products, cellulose derivatives, fatty oils, waxes, pigments, fillers or dyes and used as coatings for textiles, paper, cloth, fabrics, wood, leather, metals, stone, brick or concrete. In examples, urea is condensed with (1) propionaldehyde in the presence of butanol; (2) propionaldehyde in the presence of ethylene glycol monomethyl ether; (3) isobutyraldehyde in the presence of ethylene glycol monoethyl ether; (4) heptaldehyde in the presence of ethylene glycol monoethyl ether. The product of example 1 may be blended with toluene solutions of a castor or linseed oil modified polyhydric alcohol - polybasic acid resin.
