The invention relates to the use of special phosphoric acid estersnas emulsifiers and dispersants for pigmentsnand fillers based on polystyrene block (b) -polyalkylene oxide copolymers.n n n SO = Styroloxid, EO = Ethylenoxid, BO = Butylenoxid und. a = 1 bis < 2, b = 3 bis 100, c = 0 bis 10, d = 0 bis 3, x = 1 oder 2 sind, nwobei b>= a+c+d ist.The invention relates to block-copolymeric phosphoric acid esters and their salts of the general formula (I) [R 1 O (SO) a (EO) b (CH 2 CHCH 3 O) c (BO) d ] x PO- (OH) 3-x in which R1 = a straight-chain or branched or cycloaliphatic radical with 1 to 22 carbon atoms, SO = styrene oxide, EO = ethylene oxide, BO = Butylene oxide and. a = 1 to <2, b = 3 to 100, c = 0 to 10, d = 0 to 3, x = Are 1 or 2, where b> = a + c + d. |
