Abstract
The present invention relates to a polymer dispersion, which comprises polymer particles dispersed in an aqueous continuous phase. The polymer particles are obtainable by a radical polymerisation of one or more vinyl monomers comprising alkyl (meth)acrylates. A rosin component is dissolved into at least one of the vinyl monomers before the radical polymerisation of the vinyl monomers, and the radical polymerisation is conducted in the presence of the rosin component. The invention relates also to the use of the polymer dispersion for surface sizing of a cellulosic fibre web and to a method for producing a polymer dispersion.
