A dispersant which is a phosphate ester of a polymer which contains at least one ether group and a poly(oxyalkylenecarbonyl) chain (POAC chain) derivable from two or more different hydroxycarboxyl acids or lactones thereof. Also disclosed is the use of the dispersants in paints and printing inks including millbases. The preferred dispersants are phosphate esters of an alkyl end-capped poly(oxyalkylenecarbonyl) chain alcohol where the POAC chain is derived from &egr;-caprolactone and &dgr;-valerolactone and the alkyl group is derived from a monohydroxypolyalkyleneglycol.
一种分散剂,其为聚合物的磷酸酯,该聚合物至少含有一个醚基和可由两个或更多不同的羟基羧酸或内酯衍生的聚(氧烷基羰基)链(POAC链)。还公开了将分散剂用于包括研磨基料在内的油漆和印刷油墨中的用途。首选的分散剂是磷酸酯,其为烷基末端的聚(氧烷基羰基)链醇,其中POAC链是由&egr;-己内酯和&dgr;-戊内酯衍生的,烷基是由单羟基聚烷基乙二醇衍生的。
