摘要：
The invention relates to a copolymer which is suitable as a superplasticizer for hydraulic binders and comprises 5 to 55 mol % of an isoprenol polyether derivative structural unit, 2 to 90 mol % of an acrylic acid derivative structural unit and 2 to 90 mol % of a hydroxyalkyl acrylate structural unit.
