FIELD: chemistry.
SUBSTANCE: invention relates to a novel anti-frictional and levelling additive which contains perfluoroalkyl dicarboxylic acid/siloxane residues, and use thereof in coating materials, printing ink and plastic compositions. The invention discloses an anti-frictional and levelling additive which contains a copolymer obtained via polymerisation of A) 0.1-10 wt % mono- or diperfluoroether of a non-saturated dicarboxylic acid, B) 1-5 wt % terminal reactive polysiloxane compound, B) 50-98.9 wt % alkyl(meth)acrylate links or (meth)acrylic acid and/or another link which is deactivated from vinyl compounds, which can form radicals. The invention also discloses coating material, printing ink and a plastic composition which contains the said anti-frictional and levelling additive.
EFFECT: disclosed additive has low foaming capacity, which makes it easy to apply, and its addition to different materials reduces the coefficient of friction, improves sliding and provides complete wetting of the treated material.
