Abstract: Proposed is the use, as agents for increasing the dry strength of paper, card and cardboard, of partially hydrolysed polymers of N-vinyl carboxylic acid amides obtained by the homopolymerization of N-vinyl carboxylic acid amides of the formula (I) in which R1 and R2 are H or C1-C6 alkyl and by splitting off 0.5 to 95 mole % of the groups of the formula (II) in which R1 is H or C1-C6 alkyl.

Abstract: In a cationic modification process for starch, starch is reacted with polymers that contain amino and/or ammonium groups in an aqueous medium at temperatures from 115 to 180 ·C under an increased pressure and in the absence of oxidisers, polymerisation initiators and alkali. The reaction is conducted so that maximum 10% by weight starch has its molar weight reduced. Also disclosed is the use of the thus obtained reaction products as dry strength agents for paper.
