  • Dispersions of acrylic polymer latex as additives for the inhibition of the deposition of paraffins in crude oils and compositions that contain them
    Patent number: 7790821
    Abstract: 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.
    Type: Grant
