More Information
Summary:The present invention relates to a process of a process for preparation of a polymer dispersion comprising a step (E) of free radical polymerization in an aqueous medium (M) in the presence of: at least a pre-polymer (pO) soluble in the medium (M), at least one free-radical polymerization initiator, and at least one ethylenically unsaturated hydrophobic monomer (m) which is chosen from an alkyl (meth)acrylate of at least C6, wherein the aqueous medium (M) includes water and at least one water miscible solvent.
