Aqueous solution containing copolymers with polyether side chains

摘要

The invention relates to a method for producing an aqueous solution containing between 30 and 95 % by weight of water and between 5 and 70 % by weight of a copolymer that is dissolved in said water, by a radical solution polymerisation of an isoprenol polyether derivative with an acrylic acid derivative so that the copolymer has between 20 and 45 mol % of an isoprenol polyether derivative structural unit and between 55 and 80 mol % of an acrylic acid derivative structural unit. The aqueous solution is suitable for use as a mobile phase for hydraulic binding agents.
