Starch hybrid copolymers in the form of aqueous dispersions or water-redispersible powders, processes for producing and uses for the same. Where the starch hybrid copolymers obtainable by radically initiated polymerization in aqueous medium of ethylenically unsaturated monomers in the presence of starch or by emulsion polymerization, in aqueous medium of ethylenically unsaturated monomers in the presence of starch. The starch hybrid copolymers may also be obtainable by performing an optional subsequent drying process.
