Abstract
1449643 Preparing water-absorbent UF particles BRITISH INDUSTRIAL PLASTICS Ltd 30 May 1974 [14 June 1973] 28301/73 Headings C3R and C3C A cured particulate water-absorbent UF resin is obtained by mixing a solution of a UF resin of formaldehyde : urea molar ratio exceeding 1À2 : 1 with a hardener in the absence of sulphamic acid, ammonium hydrogen sulphate and of surface active agent. Preferably the U : F ratio is 1 : 1À3-2À0 and the UF concentration less than 30% by weight. In the example dilute H 3 PO 4 is agitated with a UF resin of U : F ratio 1 : 1À5 in water. Uses.-Fillers for aminoplast resins, plant nutrients, cosmetics bases.
