ABSTRACT Sterically stabilized aqueous polymer dispersions based on ethylenically unsaturated monomers polymerized by a free radical method and a graft polymer as protective colloid are made available by grafting the essentially hydrophobic ethylenically unsaturated monomers such as alkyl esters of acrylic acid or methacrylic acid onto the essentially water-soluble or water-dispersible polymeric protective colloid precursor by a radical method using a graft initiator, and then polymerizing ethylenically unsaturated monomers capable of free radical polymeriza- tion in an aqueous medium in the presence of the protec- tive colloid thus obtained by emulsion polymerization in the presence of a conventional free radical-forming initiator. Protective colloid precursors preferably used are polysaccharides and polymers of ethylenically unsatu- rated monomers, such as polyvinylpyrrolidone and polyvinyl alcohol in particular. The aqueous polymer dispersions, which can be processed even at room temperature, are suit- able as the base for paints or coatings.
