Abstract (en)
[origin: WO9709400A1] The invention concerns the use as thermo-thickeners of multi-block copolymers of general formula (I) or (II), in which: E designates a polyoxyalkylene sequence, each alkylene member having at most 6 carbon atoms; A designates a water-soluble polymer sequence produced from at least one monomer selected from ethylene monomers; X is a sulphur or oxygen atom; Y is an oxygen atom or an -N-R' group, R' being a linear or branched alkyl group optionally comprising at least one heteroatom and a tertiary amine group, or a C3-C8 cycloalkyl radical, or an aryl, aralkyl or alkylaryl group; R is a linear or branched alkyl, aralkyl or alkylaryl group; and n is such that the molecular mass of the multi-block copolymers Mp is greater than 250 000 g/mol.
