    摘要: A subject of the present invention is an aqueous composition combining at least one block copolymer (A) comprising, in the pH and temperature conditions of the composition, at least two polyionic blocks of the same charge and at least one non-charged block, with at least one ionic or polyionic (B) type with an opposite charge to that of the said polyionic blocks, in the pH conditions of the composition; type (B) being chosen from among ions carrying at least two charges, surfactants carrying at least one charge, oligomers and/or polymers carrying at least two charges and/or mineral particles carrying at least two charges; the block copolymer (A) content being such that the viscosity of the composition is at least greater than three times that of an aqueous solution of block copolymer (A) and to that of an aqueous solution of type (B), in the same temperature, pH and concentration conditions. The present composition, before its use or during its use, is in the form of a gel.

    摘要: A subject-matter of the present invention is a surface-active block copolymer comprising at least one hydrophilic block and at least one hydrophobic block which is prepared by a “living” or “controlled” preparation process, the said copolymer exhibiting a number-average molecular mass of between 1 000 and 50 000, preferably between 2 000 and 20 000, more preferably still between 4 000 and 16 000, a glass transition temperature of the hydrophobic block of less than 30° C., preferably of less than 25° C., and greater than −100° C., and a surface tension of less than 60 millinewtons per metre (mN/m), preferably of less than 50 mN/m, measured at a concentration in demineralized water of less than or equal to 10−4 mol/l, and the transfer agent optionally having been rendered inert with respect to the said radical polymerization. The copolymers obtained can be used in particular in detergency or in paints, adhesives and building materials.
