The invention relates to a formulation comprising an ionic compound and a polyionic polymer. The invention more specifically relates to an improved formulation thereof, further comprising a copolymer. The improved formulation avoids phase-separation of colloidal particles comprising the ionic compound and the polyionic polymer. The formulation comprises a copolymer comprising two moieties A and B, wherein moiety A is polyionic in the pH conditions of the formulation, and moiety B is neutral in the pH conditions of the formulation.

Formulation comprising an ionic compound, a polyionic polymer, and a block copolymer

The invention relates phase-separated compositions comprising two miscible solvents. More specifically, the invention relates to compositions comprising liquid droplets of an internal phase comprising a solvent B and further compounds, said droplets being dispersed in an external phase comprising solvent A, wherein solvent A and solvent B are miscible. Such compositions find use in various technical fields, including encapsulation, vectorisation, protection of compounds, separations, and chemical reactions in a dispersed medium.

The invention concerns a method for controlling the stability of an emulsion comprising a hydrophobic phase dispersed in an aqueous phase, or an aqueous phase dispersed in a hydrophobic phase, and less than 4% by weight of a surfactant, said process comprising the step of using in the emulsion a block copolymer.

Method for controlling the stability of emulsions

The invention relates to a block copolymer and more especially to a thermoplastic elastomer block copolymer. The block copolymer is a diblock (block A)-(bloc B) copolymer, a triblock (block A)-(block B)-(block A), or a triblock (block A)-(block B)-(block C) copolymer, wherein block A is a stiff block, block B is a soft block, and block C is a stiff block. Block A or Block B comprises repetitive units deriving from segregation monomers.

The invention relates to a gelling aqueous composition comprising block copolymers containing at least one water-soluble block and at least one block predominantly hydrophobic in nature, and forming a viscoelastic gel.

Gelled aqueous composition comprising a block copolymer containing at least one water-soluble block and one hydrophobic block

The invention relates to water-soluble block copolymers comprising at least one block of hydrophobic nature and at least one block of hydrophilic nature, the block of hydrophobic nature exhibiting hydrophilic units in an amount of between 33% and 99% by weight with respect to the total weight of the units of the hydrophobic block. These copolymers are preferably diblocks or triblocks and are prepared by a polymerization process referred to as a living or controlled. Control of their hydrophilic-lipophilic balance makes it possible to adjust their solubility in water and their self-association properties. These copolymers can be used in particular as adhesion agents or wetting agents.
