摘要： A biological method is for obtaining an MO monomer including an ethylenic unsaturation by bioconversion of a CN compound including at least one nitrile function. The CN compound is at least partially renewable and non-fossil. The biological method includes at least one step of enzymatic bioconversion of the CN compound in the presence of a biocatalyst including at least one enzyme.

摘要： The present invention relates to a crosslinked copolymer obtained by precipitation polymerization of at least one monomer comprising at least one carboxylic acid function, at least one hydrophobic monomer, and at least one crosslinking agent. The copolymer is mainly characterized in that 30 mol % to 90 mol % of the carboxylic acid functions are in salified form prior to the precipitation polymerization, the solvent used for the precipitation polymerization comprises at least one alcohol comprising 1 to 4 carbon atoms, and the copolymer is obtained in the absence of water-soluble non-ionic monomers.

摘要： A device for dispersing a water-soluble polymer in powder form having a standard particle size of less than 1 mm, includes: a wetting chamber, a chamber for grinding and discharging the dispersed polymer with a horizontal axis of revolution, and a mechanism for connecting the wetting chamber to the grinding chamber in the form of an L-shaped tube. The upper and lower parts of the wetting chamber and the L-shaped tube have an internal surface with an identical surface tension (TS1). The cover of the wetting chamber has an internal surface with a surface tension (TS2) higher than the surface tension (TS1) of the internal surface of the upper and lower parts of the wetting chamber and the L-shaped tube.

摘要： A method for spraying a mixture comprising at least a first liquid in the form of a liquid preparation of water-soluble or water-swellable polymers and at least a second liquid, characterized in that it implements a nozzle for simultaneously spraying at least two liquids, comprising: •a body provided with a first chamber within which a first liquid flows and a second chamber within which a second liquid flows, each of the two chambers having a through-hole on the outside of the body, •a deflector secured to the body arranged downstream from at least one of the through-holes, in the direction of flow of the first and second liquids, said deflector being capable of modifying the direction of flow of the first and second liquids. The invention also relates to a nozzle for implementing the method.
