    Abstract: A method for modifying starch by heating the starch in an aqueous medium to temperatures greater than the pasting temperature of the starch in the presence of (a) a polymer cationization agent selected from the group consisting of polymers with molecular weights up to 1 million containing vinylamine units, polyethylene imines, polydiallyldimethylammonium chlorides, condensates of dimethylamine with epichlorohydrin or dichloroalkanes, condensates of dichloroethane and ammonia and mixtures of the above mentioned compounds, and (b) polymer dehydrators for paper selected from the group consisting of water-soluble, crosslinked polyamidoamines that are optionally grafted with ethylene imine, polymers with molecular weights of greater than 1 million containing acrylamide and/or methacrylamide units, polymers with molecular weights of greater than 1 million containing vinylamine units and mixtures of said compounds. Also disclosed are reaction products obtained by the inventive method and the use of the reaction products as dry-strength agents in the production of paper, board and paperboard.
