The invention relates to the use of a co-polymer (A), which may be produced by means of radical polymerisation of a) at least one olefinic unsaturated monomer and b) at least one olefinic unsaturated monomer, different from olefinic unsaturated monomer (a), of general formula (I) R1R2C=CR3R4 (I), where the groups R1, R2, R3 and R4 independently = H, substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl, with the proviso that at least two of the variables R1, R2, R3 and R4 = substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl, in particular substituted or unsubstituted aryl, in an aqueous or organic medium, for the production of functional organic powders, in particular fillers for coating materials, adhesives and sealing masses of all types.
L'invention concerne l'utilisation d'un copolymérisat (A), obtenu par polymérisation radicalaire a) d'au moins un monomère oléfiniquement insaturé et b) d'au moins un monomère oléfiniquement insaturé, différent du monomère oléfiniquement insaturé (a), de formule générale R?1¿R?2¿C=CR?3¿R?4¿ (I), dans laquelle les restes R?1¿, R?2¿, R?3¿ et R?4¿ représentent chacun indépendament les uns des autres des atomes d'hydrogène ou des restes alkyle, cycloalkyle, alkylcycloalkyle, cycloalkylalkyle, aryle, alkylaryle, cycloalkylaryle, arylalkyle ou arylcycloalkyle substitués ou non, à condition qu'au moins deux des variables R?1¿, R?2¿, R?3¿ et R?4¿ représentent des restes aryle, arylalkyle ou arylcycloalkyle substitués ou non, en particulier des restes aryle susbitués ou non, dans un milieu aqueux ou organique, pour la production de poudres organiques fonctionnelles, en particulier de charges pour substances de revêtement, adhésifs et masses d'étanchéité de tout type.
