ABSTRACT:
The invention pertains to an aqueous dispersion of an acrylic polymer stabilized by a compound obtained by copolymerizing specific amounts of (1) styrene and/or methyl styrene, (2) (meth)acrylic acid and/or an amino group-containing (meth) acrylic ester, and optionally another comonomer, in the presence of a specific polybutadiene, the carboxylic acid groups and/or amino groups being at least partly ionized. The invention also pertains to a coating composition based on such aqueous dispersion and to a substrate coated with said coating composition. Finally, the invention also relates to a process for the preparation of the stabilizer of the aqueous dispersion of an acrylic polymer.
