(7) II-a)An aqueous phase is prepared by successively pouring, into a beaker and with stirring, 277 grams of a commercial solution containing 50% by weight of acrylamide, 375 grams of an aqueous solution containing 55% of the sodium salt of 2-methyl-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid, 10.8 grams of glacial acrylic acid, 0.058 gram of methylenebis(acrylamide), 0.45 gram of a commercial aqueous solution containing 40% by weight of sodium diethylenetriamine pentaacetate, and 5.3 grams of an aqueous solution containing 48% by weight of sodium hydroxide to adjust the pH of this aqueous phase to 5.3.

(8) An organic phase is independently prepared by mixing 130 grams of polyisobutene, 90 grams of Isopar H, 30 grams of Marcol 52, 17.0 grams of Montane 70, 5 grams of Simaline IE 200 and 0.2 gram of azobis(isobutyronitrile) (AIBN).

(9) The aqueous phase prepared is subsequently gradually added to the oily phase and then dispersed using a rotor-stator of Ultra-Turrax type sold by the company IKA.

(10) The emulsion obtained is transferred into a reactor, subjected to sparging with nitrogen to remove the oxygen, and cooled to about 5-6 C. 5 cm.sup.3 of a solution containing 0.42% by weight of cumene hydroperoxide in Isopar H are added to the emulsion with continuous stirring, followed by gradual introduction of an aqueous solution containing 0.1% by weight of sodium metabisulfite at a flow rate of 0.5 cm.sup.3 per minute to initiate the polymerization reaction. The temperature of the medium increases up to a steady stage.

(11) After maintaining at 80 C. for one hour, the Isopar H is removed from the reaction medium by partial vacuum distillation, as is most of the water. The reaction medium is then cooled to approximately 35 C. to obtain the mixture denoted (M.sub.1).

(12) The mixture (M.sub.1) obtained above is divided up into different portions, to which the different surface-active compositions (EM.sub.1), (EM.sub.2) and (EM.sub.3), as described above, preheated to 60 C., are added in proportions by weight as shown in table 2 below.

(13) The self-invertible inverse latexes resulting from these mixtures are respectively denoted (IL.sub.1), (IL.sub.2) and (IL.sub.3) and are evaluated by the observation of their appearance at 25 C., by the rate of inversion during the preparation of an aqueous gel comprising 2% by weight of self-invertible inverse latex (the method of which is described below) and by the viscosity of this aqueous gel comprising 2% by weight of a self-invertible inverse latex.

(14) The method for evaluation of the duration of inversion of the self-invertible inverse latexes consists in introducing, into a 2 liter beaker, the amount of water necessary for the preparation of 800 grams of an aqueous gel. A mechanical helical stirrer of Turbotest type, version 2004, sold by the company VMI, connected to a motor, is placed toward the bottom of the beaker. Stirring is started at a speed of 900 revolutions/minute and the necessary amount of self-invertible inverse latex to be evaluated is introduced into the beaker with stirring. This stirring creates a vortex which disappears when the polymer inverts and the gel is formed. The duration of inversion, measured in seconds, of the self-invertible inverse latexes corresponds to the time elapsed between the start of the addition of the self-invertible inverse latex tested and the disappearance of the vortex, resulting in a smooth gel, devoid of lumps, being obtained. This evaluation is carried out on conclusion of the manufacture of the inverse latexes tested (t=0) and then after a period of storage at 25 C. of 2 months (t=2 months). The results obtained are given in table 2 below. The viscosity of an aqueous gel comprising 2% by weight of self-invertible inverse latex () is measured at t=0 and then at t=2 months, by means of a Brookfield RVT viscometer (Spindle 6 Speed 5). Likewise, the appearance of the self-invertible inverse latex is evaluated visually at t=0.

(16) The self-invertible inverse latexes (IL.sub.2) and (IL.sub.3) according to the invention and free of alkoxylated derivatives make it possible to obtain smooth gels, with a duration of inversion far lower than that observed for the self-invertible inverse latex (IL.sub.1), comprising only decaglycerol monolaurate alone as constituent of the inverting surface-active system, while retaining excellent thickening properties. Furthermore, they are characterized by better reproducibility of the rate of inversion and of the thickening properties after two months of storage than for the comparative self-invertible inverse latex (IL.sub.1).

IIIPreparation and Evaluation of Self-Invertible Inverse Latexes of a Crosslinked Copolymer of the Sodium Salt of 2-Methyl-2-[(1-Oxo-2-Propenyl)Amino]-1-Propanesulfonic Acid and of Acrylamide

(18) An organic phase is independently prepared by mixing 220 grams of Emogreen L15 and 25 grams of Simaline IE.

(19) The aqueous phase prepared is subsequently gradually added to the oily phase and then dispersed using a rotor-stator of Ultra-Turrax type sold by the company IKA.

(20) The resulting emulsion is transferred to a reactor to be subjected to nitrogen bubbling in order to remove the oxygen and cooled to about 5-6 C. 0.69 gram of sodium persulfate dissolved beforehand in 2 grams of water is added to the emulsion, with the stirring being maintained, then an aqueous solution containing 2.25% by weight of sodium metabisulfite is gradually introduced in order to initiate the polymerization reaction. The temperature of the medium increases up to a steady stage.

(21) After maintaining at 80 C. for three hours, the reaction medium is then cooled to approximately 35 C. to obtain the mixture denoted (M.sub.2).

(22) The mixture (M.sub.2) obtained above is divided up into different portions, to which the different surface-active compositions (EM.sub.1), (EM.sub.2) and (EM.sub.3), as described above, preheated to 60 C., are added in proportions by weight as shown in table 3 below.

(23) The self-invertible inverse latexes resulting from these mixtures are respectively denoted (IL.sub.4), (IL.sub.5) and (IL.sub.6) and are evaluated by the observation of their appearance at 25 C., by the rate of inversion during the preparation of an aqueous gel comprising 2% by weight of self-invertible inverse latex (the method of which is described below) and by the viscosity of this aqueous gel comprising 2% by weight of a self-invertible inverse latex.

This evaluation is carried out at the end of the production of the tested inverse latexes (t=0). The results obtained are given in table 3 below. The viscosity of an aqueous gel comprising 2% by weight of self-invertible inverse latex (M) is measured at t=0 by means of a Brookfield RVT viscometer (Spindle 6 Speed 5). Likewise, the appearance of the self-invertible inverse latex is evaluated visually at t=0.
