Abstract (en)

[origin: WO0068310A1] The invention relates to antistatic compositions of cationic latexes of copolymers of vinyl aromatic compounds, alkyl esters of (meth)acrylic acid and amine containing monomers wherein said compositions contain hollow particle latexes as polymeric filler. Fillers are prepared by using anionic surfactants and recharged with other surfactants in order to eliminate the latex coagulation in the preparation of the antistatic compositions.
