water soluble hydrophobic association copolymer, process for preparing a water soluble hydrophobic association copolymer, and use of the copolymers

摘要

1/1 summary “water soluble hydrophobic pool copolymer, a process for the preparation of a water soluble hydrophobic pool copolymer, and, Use of the Copolymers The present invention relates to water-soluble hydrophobic association copolymers which are obtained in the presence of a surface active compound. polymerizable and comprising new association monomers in a hydrophobic manner. the monomers comprise an ethylene unsaturated group and a polyester block, the polyester block comprising a hydrophilic polyethylenoxy block and a hydrophobic polyalkylenoxy block consisting of alkylenoxy units having at least 4 carbon atoms. monomers may optionally have a terminal polyethylenoxy block. The invention further relates to processes for preparing and using the copolymers.
