Abstract: Process for manufacturing a formulation of a chelating agent according to general formula (I): R1—CH(COOX1)—N(CH2COOX1)2, wherein R1 is selected from C1-C4-alkyl, linear or branched, phenyl, benzyl, CH2OH, and CH2CH2COOX1, X1 is (MxH1-x), M being selected from alkali metal, x is in the range of from 0.6 to 1, said formulation comprising in the range of from 0.01 to 20% by weight of water, and at least one organic solvent selected from alkanols with a boiling point at normal pressure that is higher than the boiling point of water, from alkandiols, alkantriols and polyols and mixtures of at least two of the foregoing, said process comprising the following steps: (a) providing an aqueous solution of chelating agent according to general formula (I), (b) adding said organic solvent and (c) removing the water completely or the majority of the water by distillation.

Abstract: The present invention relates to a process for preparing hydrophobically associating macromonomers M and to the novel macromonomers prepared by means of the process according to the invention. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form, the latter consisting of a polyethyleneoxy block and a hydrophobic polyalkyleneoxy block consisting of alkyleneoxy units having at least 4 carbon atoms. Optionally, the macromonomers M may have a terminal polyethyleneoxy block. The macromonomers prepared by the process according to the invention are suitable for reaction with further monomers, especially with acrylamide, to give a water-soluble, hydrophobically associating copolymer.

Abstract translation: 本发明涉及制备疏水缔合大分子单体M和通过本发明方法制备的新型大分子单体的方法。 大分子单体M包括可共聚的烯键式不饱和基团和嵌段形式的聚醚结构，后者由聚乙烯氧基嵌段和由具有至少4个碳原子的亚烷氧基单元组成的疏水聚亚烷基氧基嵌段组成。 任选地，大分子单体M可以具有末端聚乙烯氧基嵌段。 通过根据本发明的方法制备的大分子单体适用于与其它单体，特别是与丙烯酰胺反应，得到水溶性疏水缔合共聚物。
