This invention relates to latex dispersions that are based on (co)polymers with one or more n-alkyl(meth)acrylate monomers with n a varying from 6 to 40, and optionally one or more monomers that are not very water-soluble of the (meth)acrylic and/or vinyl type, optionally one or more polar monomers that are selected from among the (meth)acrylamides and their derivatives and optionally one or more monomers that are selected from among the ethylenically unsaturated monocarboxylic and/or dicarboxylic acids or anhydrides. These dispersions are obtained by radical-type emulsion polymerization in the presence of water. They can be used as is for the inhibition of the deposition of paraffins that are contained in the crude petroleum hydrocarbons or else diluted in one or more solvents.

Dispersions of acrylic polymer latex as additives for the inhibition of the deposition of paraffins in crude oils and compositions that contain them

The invention relates to novolac alkylphenol resins having a low level of free alkylphenol, a method for the production thereof, and the use thereof as tackifying resins and reinforcing resins for rubbers. The resins may be used advantageously in the production of tires.

The invention relates to a composition comprising a compound of formula (I): R&#x2014;B&#x2014;Ro&#x2014;Z and a compound of formula (II): and/or their reaction product.

Surface treatment composition and process

The invention relates to fluorinated copolymers resulting from the polymerization of a polyfluorinated monomer, a (meth)acrylate amino alcohol, vinyl acetate and a silane monomer in a distillable organic solvent, aqueous compositions containing them, and their use for treating solid substrates, notably building materials.

Fluorinated copolymers for hydrophobic and oleophobic treatment of building materials

The invention discloses a process for the preparation of fluorinated polymers by miniemulsion polymerization of a mixture of fluorinated and nonfluorinated monomers in the absence of organic solvent. This polymerization process makes it possible to obtain an aqueous emulsion of fluorinated polymers devoid of coagulum.

Polymers fluorinated by polymerization in mini-emulsion

Fluorocopolymers resulting from the polymerization of a polyfluoromonomer, of an aminoalcohol (meth)acrylate and of methacrylic acid in a distillable organic solvent, and aqueous compositions containing them.
