Definitions
- the invention relates to a thickening (meth)acrylic copolymer prepared using a polyalkoxylated Guerbet alcohol comprising a doubly branched alkyl group.
- the method for preparing this copolymer and its use in aqueous compositions, in particular in coating compositions, also form part of the invention.
- aqueous hydraulic binder compositions are known, aqueous adhesive compositions, aqueous detergent compositions, aqueous cosmetic compositions, aqueous ink compositions, aqueous paper coating compositions, aqueous coating compositions, in particular aqueous varnish compositions or aqueous paint compositions, for example aqueous decorative paint compositions or aqueous industrial paint compositions.
- these aqueous compositions must have a texture suitable for their use or storage. In particular, they must have a suitable viscosity.
- these aqueous compositions must be able to be used under conditions which can vary widely.
- the viscosity of these aqueous compositions may vary or deteriorate.
- the functional properties of these aqueous compositions can therefore be altered if their rheological behavior is not suitable, for example to prevent sedimentation or phase separation phenomena during storage time, which can also be manifested by variations in viscosity. .
- Such variations or degradations are particularly detrimental or damaging for aqueous hydraulic binder compositions, for aqueous adhesive compositions, for aqueous detergent compositions, for aqueous cosmetic compositions, for aqueous ink compositions, for aqueous coating compositions. of paper, for aqueous coating compositions, in particular for aqueous varnish or paint compositions.
- aqueous coating compositions in particular aqueous varnish or paint compositions, whose viscosity is adapted to allow the maintenance of their homogeneity as well as the integrity of their functional properties. Maintaining viscosity and limiting viscosity loss of these aqueous compositions should be possible over wide ranges of shear gradient.
- aqueous coating compositions use rheology modifying polymers. These polymers should make it possible to give aqueous compositions the desired rheological properties for wide ranges of shear rates. These polymers should also improve the shear thinning of these aqueous compositions by giving them sufficient pseudo-plasticity, ensuring their stability and homogeneity during their storage life, facilitating their transfer to application tools and helping to limit the appearance drips once applied.
- the compatibility of the different constituents of an aqueous coating composition must also be taken into account. In particular, it is important that the thickening copolymer and the pigments and binders used have good compatibility.
- aqueous coating compositions in particular paint compositions and particularly with regard to the addition of pigment concentrates used for coloring.
- pigment compatibility Without good pigment compatibility, the rheology of the composition can be significantly degraded. Insufficient pigment compatibility can also lead to a reduction in color strength and result in an uneven or washed out shade, which may result in the use of a higher quantity of pigment or the presence of aesthetic defects in the final coating.

- the copolymer (PI) is obtained at 30.4% by weight of dry extract, the composition of which is detailed in Table 1.
- disposable syringe type weigh 10.42 g of monomer (h) (sodium salt of 2-acrylamido-2-methylpropane sulfonic acid) at 50% by weight in water.
- the contents of the reactor are heated to a temperature of 85°C ⁇ 2°C.
- the reagents from the 3 containers are introduced into the polymerization reactor at a temperature of 85°C ⁇ 2°C.
- a copolymer (P2) with 30.0% by weight of dry extract is obtained, the composition of which is detailed in Table 1.
- the contents of the reactor are heated to a temperature of 85°C ⁇ 2°C.
- the reagents from the 3 containers are introduced into the polymerization reactor at a temperature of 85°C ⁇ 2°C.
- a copolymer (P3) with 30.2% by weight of dry extract is obtained, the composition of which is detailed in Table 1.
- the contents of the reactor are heated to a temperature of 85°C ⁇ 2°C.
- the reagents from the 2 containers are introduced into the polymerization reactor at a temperature of 85°C ⁇ 2°C.
- a copolymer (P4) with 30.0% by weight of dry extract is obtained, the composition of which is detailed in Table 1.
- the paint formulation is colored by adding 5% by weight of a black pigment
- the aqueous formulations F2 and F3 are prepared according to the invention by replacing the copolymer composition PI respectively by the copolymer compositions P2 and P3 according to the invention.
- the pigment compatibility of formulations Fl, F2 and F3 is evaluated on a dry paint film.
- the coloring of the initially white paint is obtained by adding 5% of coloring based on black pigment (Colanyl N500 black Clariant), percentage calculated in relation to the weight of the white paint formulation.
- the test known as such, of rubbing the colored paint with a finger and applied to a wet thickness of 150 micrometers on a contrast card (rub test) makes it possible to subject a small part of the surface of the paint film freshly applied color with a shearing effect generated by a circular movement of the finger.
- the shearing effect can modify the stability and distribution of the colored pigment in the matrix that constitutes the colored paint film and consequently, the intensity of the coloring at the location of the sheared area.
- the color difference between the zone of the colored paint film initially sheared and the zone of non-sheared colored paint is measured using a spectrophotometer of the spectro-guide sphere gloss type marketed by the Byk company.
- the color difference is quantified by the AE value calculated from the measurement parameters corresponding to the known color space L*a*b*.
- a low AE value means a reduced color difference between the sheared zone and the non-sheared zone, and therefore an improvement in pigment compatibility.
- the area of unsheared colored paint is also measured corresponding to one of the parameters of the L*a*b* color space.
- the L* parameter quantifies the intensity of the coloring.
- a low value for the L* parameter means reduced clarity and therefore a greater black intensity corresponding to a improvement of the pigment compatibility of the paint formulation evaluated in which the copolymer according to the invention is used.
- the results are presented in Table 3.
- the copolymers according to the invention make it possible to properly control the different components of viscosity, both after preparation and over time.
- the copolymers according to the invention confer good pigment compatibility to these paint formulations.
