摘要：
The invention relates to a process for the preparation of an aqueous solution comprising 30 to 95% by weight of water and 5 to 70% by weight of a copolymer dissolved in the water by free radical solution polymerizations of an isoprenol polyether derivative with an acrylic acid derivative, so that the copolymer has 20 to 45 mol % of an isoprenol polyether derivative structural unit and 55 to 80 mol % of an acrylic acid derivative structural unit. The aqueous solution is suitable as a superplasticizer for hydraulic binders.
