Definitions
- the invention relates to the field of LCST macromonomers, a process for obtaining said macromonomer and the copolymers comprising said macromonomers.
- Water-soluble polymers with a thickening effect are used in many fields such as cosmetics, detergents, printing inks, dispersion paints, textiles, civil engineering, construction, but also in enhanced oil and gas recovery.
- thermosensitive There are many different chemistries, known to those skilled in the art, of polymers which can be used as thickeners.
- An important class of polymers is called thermosensitive. These polymers have pendent or chain-end groups that have an LCST (lower critical demixing temperature). These LCST groups correspond to groups whose solubility in water for a given concentration is modified beyond a certain temperature and according to salinity.
- the aqueous solution comprising the polymer does not comprise gel particles. Indeed, even small, these gel particles whose dimensions are of the order of a micrometer can strongly affect the thickening performance during use.
- the object of the present invention is therefore to provide heat-sensitive copolymers, that is to say copolymers obtained by polymerization of one or more macromonomers with LCST.
- the invention aims to provide such copolymers whose effect as a thickening agent is at least equal to that of the polymers of the prior art and which, during their uses, are free of gel particles. Disclosure of Invention

- anionic monomer chosen from acrylic acid, methacrylic acid, itaconic acid, crotonic acid, maleic acid, fumaric acid, 2-acrylamido acid 2-methylpropane sulfonic, vinylsulfonic acid, vinylphosphonic acid, allylsulfonic acid, allylphosphonic acid, styrenesulfonic acid

- - R ⁇ and R ⁇ ’ are the -CH2-CH3 group
- the LCST groups correspond to groups whose solubility in water for a given concentration is modified beyond a certain temperature and as a function of salinity. These are groups exhibiting a transition temperature by heating defining their lack of affinity with the solvent medium. The lack of affinity with the solvent results in an opacification or a loss of transparency.
- the minimum transition temperature is called “LCST” (lower critical solution temperature). For each group concentration at LCST, a heating transition temperature is observed. It is greater than the LCST which is the minimum point of the curve. Below this temperature the macromonomer is soluble in water, above this temperature the macromonomer loses its solubility in water.
- the measurement of the LCST can be done visually: the temperature at which the lack of affinity with the solvent appears, i.e. the cloud point, is determined.
- the cloud point corresponds to the opacification of the solution or loss of transparency.
- the LCST can also be determined according to the type of phase transition, for example by DSC (differential scanning calorimetry, from the English acronym “Differential Scanning Calorimetry”), by a measurement of transmittance or by a measurement of viscosity.
- DSC differential scanning calorimetry, from the English acronym “Differential Scanning Calorimetry”
- the LCST is determined by determining the cloud point by transmittance according to the following protocol.
- the transition temperature is measured for a compound at LCST for a solution having a mass concentration in deionized water of 1% by weight of said compound.
- the cloud point corresponds to the temperature at which the solution has a transmittance equal to 85% of light rays having a wavelength between 400 and 800 nm.
- the temperature at which the solution has a transmittance equal to 85% corresponds to the minimum transition temperature LCST of the compound, in this case from the macromonomer to LCST.
- a transparent composition has a maximum transmittance value of light, whatever the wavelength between 400 nm and 800 nm, through a sample 1 cm thick, at least 85%, preferably at least 90%. This is why the cloud point corresponds to a transmittance of 85%.

- Preparation of the macromonomer at LCST as described above includes:
- telomeres are synthesized by telomerization using a telogenic agent. Telomerization favors the synthesis of low molecular weight LCST oligomers (called telomeres).
- the "monomers A, B, and C” refer both to the monomers whose telomerization leads to the telomere at LCST, and to the constituent monomers of the telomere and of the macromonomer obtained by polymerization of the telomere with a compound containing a carbon-carbon double bond. It will however be understood that within the telomere and the macromonomer, the monomers A, B, and C are no longer capable of reacting by polymerization, since they have already polymerized with each other, and are therefore linked between them. Within the telomere and macromonomer, monomers A, B, and C can also be referred to as "motifs" or "monomer units".
