Definitions
- the field of the invention relates to zwitterionic monomers and more specifically to novel sulfobetaine monomers, as well as their preparation process and their use to produce (co) polymers.
- Zwitterionic monomers have the particularity of having at least one anionic charge and at least one cationic charge on the same monomer unit.
- the cationic group is generally a quaternary ammonium.

- the synthesis protocol is that described above.
- Table 5 Compositions and characteristics of tests 5-1 and 5-2
- FIG. 22 corresponds to the graph of the evolution of the pressure difference dP between the inlet and the outlet of the porous medium, as a function of the temperature with a change from 25 ° C to 95 ° C.
- the graph in figure 22 shows an increase in the pressure differential inside the section with temperature (from 25 ° C to 95 ° C). This confirms the thermo-swelling and thermo-aggregating performances of the particles of test 5-1 as a function of the temperature.
- this example 17-E demonstrates that the emulsions of polymer particles prepared from the monomers of the invention have properties of propagation, heat-swelling and heat-aggregation in a porous medium.
- Example 18 Dishwashing liquid formulated from a MAAMPS copolymer
- the detergency industry formulates foaming products from many raw materials including surfactants. Excipients can be added to formulations by those skilled in the art in order to increase the foaming properties of the formulations, or even to stabilize the foam formed.
- the objectives of this new test are to evaluate the foaming and stabilizing properties of the foams formed in the presence of fatty residues, of additives prepared from one of the monomers of the invention.
- a copolymer of acrylamide (AM) and MAAMPS has been prepared by conventional radical polymerization in solution in water.
- the chemical composition is collected in Table 6.
- Formulations F, G, H, I, and J are respectively packaged in graduated test tubes.
- the volume of each of the solutions occupies, at start-up, 1/3 of the volume of the test tube.
- Nine cycles of twenty rotations (30 rpm) each are then carried out on each of the specimens.
- Five milliliters of olive oil are added to each test tube (ie a total of 40 mL, at the end of the procedure).
- the foam heights of tests G, H, I, J are then measured and compared with that of test F. The results obtained are collated in Table 9.
- the objectives of this new test are to evaluate the properties of total retention (FPR, Fibers + Mineral Loads), Mineral Load Retention (FPAR) and Vacuum Drainage (DDA).
- FPR total retention
- FPAR Mineral Load Retention
- DDA Vacuum Drainage
- Example 10 The polymers below were synthesized by following the procedure described in Example 1.
- the formulation of test 7-0 does not contain a polymer.
- Table 10 summarizes the chemical compositions and the performances (concentration of 0.25% by mass in the paper formulation) of the various tests.
- the molar masses of the various copolymers are comparable and of the same order of magnitude.
- the tests according to the invention generate higher FPAR and FPR values than the reference, and DDA values lower than the reference.
- This new example demonstrates that the terpolymers prepared from the sulfobetaine monomers of the invention demonstrate good performance in total retention, in charge retention and in vacuum drainage (drainage).
- Example 20 High viscosity additive (HVFR) for hydraulic fracturing
- the hydraulic fracturing industry uses many additives including friction reducers which induce high viscosities in saline aqueous media (HVFR for High Viscous Friction Reducer).
- HVFR High Viscous Friction Reducer
- the objectives of this example are to formulate fracturing fluids hydraulic from additives (of the invention and of the prior art) and to see the “bulk” viscosity levels obtained.
- Table 11 The polymers described in Table 11 were synthesized by following the procedure described in Example 1. Table 11 summarizes the chemical compositions and the characteristics of each of the tests. The molar masses of the various copolymers are comparable and of the same order of magnitude.
- Brine 1 is composed of sodium chloride (30 g / L) and calcium dichloride (3 g / L).
- Brine 2 is composed of sodium chloride (85 g / L) and calcium dichloride (33 g / L).
- Fann viscosities The Fann viscosities, in centipoise (cP) are measured at 20 ° C using the Chandler Engineering model 3500 viscometer which is equipped with the R1B1 module (Rotor 1 Bob 1). The values of the Fann viscosities at the shear gradients of 511 and 102 s 1 are extrapolated by applying the angular speeds of 300 and 60 rpm (revolutions per minute) respectively.
- Tests 8-1 and 8-2 generate higher Fann viscosities than for Tests 8-3, regardless of the shear (100 or 511 s-1) and the dosage (4 or 6 Gallon per Thousand).
- This new example demonstrates that hydraulic fracturing fluids of the type (HVFR) formulated from emulsions produced from the monomers of the invention have Higher Fann viscosities than those of the fluids prepared from the emulsions of the prior art, and thus offer better performance in the intended application.
- HVFR hydraulic fracturing fluids of the type
