摘要 |
The present invention relates to a process for the preparation of hydrophobically associating macromonomers M and to the novel macromonomers produced by the inventive method. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form which comprises a polyethylenoxy block and a hydrophobic polyalkylenoxy block consisting of alkylenoxy-units with at least 4 carbon atoms. Optionally, the macromonomers M may comprise a terminal polyethylenoxy block. The macromonomers produced by the inventive method are suitable for reaction with other monomers, in particular with acrylamide, to form a water-soluble, hydrophobically associating copolymer. |
