WATER-SOLUBLE HYDROPHOBICALLY ASSOCIATING COPOLYMERS HAVING NOVEL HYDROPHOBICALLY ASSOCIATING MONOMERS

摘要

The present invention relates to a water-soluble hydrophobic associative copolymer obtained in the presence of a non-polymerizable surface-active compound and comprising a novel hydrophobic associative monomer. The monomer includes an ethylenic saturated group and a polyether block (the polyether block includes a hydrophilic polyethyleneoxy block and a hydrophobic polyalkyleneoxy block composed of alkyleneoxy units having 4 or more carbon atoms). The monomer can optionally have a terminal polyethyleneoxy block. The invention further relates to a process for the preparation of the copolymer and the use thereof.
