- copolymers have a solubilization or a faster dispersibility in water at neutral pH or close to neutral than copolymers known from the prior art.
- This invention is appreciated in various uses of these copolymers as pigment dispersing agents, as rheology modifiers in applications as diverse as drilling muds, textile printing pastes, cosmetics, or detergents, coatings such as anti-sedimentation and / or suspending agents for coarse mineral or organic fillers for example in phytosanitary applications, but especially in the three-dimensional printing (or 3D printing) of an object and more particularly as sacrificial materials modeling by deposition of molten filaments.
- this technology makes it possible to manufacture English: "additive manufacturing” or AM) a real object from a virtual object. It is based on the cutting of the 3D virtual object in 2D strips of very thin thickness. These thin strips are deposited one by one by fixing them on the previous ones, which reconstitutes the real object.
- materials constituting the object are plastic materials (especially acrylonitrile butadiene styrene (or ABS) and polylactic acid (or PLA)), wax, metal or ceramics.
- additive techniques are the deposition of fused deposition (FDM) and laser sintering (laser sintering).
- Molten filament deposition modeling is a mechanical technique that consists in melting a filament of synthetic material (generally ABS or PLA type plastic) through an extrusion nozzle heated to a temperature of between 160 and 270 ° C. From this nozzle comes a molten filament with a diameter of about one-tenth of a millimeter. This wire is deposited online and is sticking by re-fusion on what has been filed beforehand.
- This technique makes it possible to create parts made of good material, having mechanical, thermal and stability characteristics identical to injected thermoplastic parts.

- compositions have a kinetics of solubilization or dispersibility in water still too slow, moreover at neutral pH.
- Increasing the proportion of hydrophilic monomers could be a solution, but in this case other important characteristics such as Tg, thermal stability, melt flow or mechanical properties are degraded.
- composition comprising a random copolymer comprising methacrylic acid, butyl acrylate, styrene and an additional hydrophilic monomer judiciously chosen has a much faster dissolution or dispersibility at neutral pH or near neutral, that is to say between 5.5 and 9.5, than the known compositions of the prior art.
