A dispersion of non-crosslinked copolymer of methyl acrylate and of acrylic acid in a 95/5 ratio, in isododecane, was prepared according to the method of Example 7 of document EP-A-749 747. A dispersion is thus obtained of particles of poly(methyl acrylate/acrylic acid) surface-stabilized in isododecane with a polystyrene/copoly(ethylene-propylene) diblock block copolymer sold under the name Kraton G1701 (Shell), with a solids content of 24.2% by weight, a mean particle size of 180 nm and a Tg of 20° C. This copolymer can form a film at room temperature.
