CA 2394029
The invention relates to aqueous primary dispersions and coating matters containing dispersed and/or emulsified, solid and/or liquid polymer particles and/or dispersed solid core-shell particles having a particle diameter <= 500 nm. The inventive dispersions and coating matters can be produced by means of radical micro or miniemulsion polymerisation of at least one olefinically unsaturated monomer (A) in the presence of at least one hydrophobe cross- linking agent for the (co)polymer resulting from the monomer or the monomers (A). The invention also relates to a method for producing same and to the use thereof.
La présente invention concerne des dispersions primaires et des substances de revêtement aqueuses, qui contiennent des particules polymères solides et/ou liquides, en dispersion et/ou en émulsion, et/ou des particules noyau-couches solides, en dispersion, d'un diamètre particulaire <= 500 nm, pouvant être produites par polymérisation radicalaire en microémulsion ou en miniémulsion, d'au moins un monomère oléfiniquement insaturé (A), en présence d'au moins un agent de réticulation hydrophobe, destiné au (co)polymère résultant du/des monomère(s) (A). La présente invention concerne également un procédé de production de ces dispersions primaires et substances de revêtement aqueuses, ainsi que leur utilisation.
