반응 단계

5 parts of sodium polyacrylate (molecular weight about 200,000) are dissolved in 277 parts of water. 5 parts of the oxyalkylation product obtained by reacting 1 mole of di-(α-phenylethyl)-phenol first with 7 moles of propylene oxide and then with 20 moles of ethylene oxide, 10 parts of urea and 3 parts of diammonium phosphate are added to the solution. After a brief period, a homogeneous mixture is obtained, to which 500 parts of gasoline (boiling range 140° - 200° C) and 200 parts of a 40% strength aqueous dispersion of a copolymer of 65 parts of butyl acrylate, 24 parts of styrene, 6 parts of ethyl acrylate and 5 parts of N-methylolmethacrylamide are added, with vigorous stirring (3,000 rmp). A very stable oil-in-water emulsion is obtained, which is particularly suitable for use as a carrier for organic pigments.
