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.

Abstract: Paper, board and cardboard are produced by draining a pulp slurry in the presence of high molecular weight, water-soluble polymers of N-vinylamides as drainage aids, retention agents and flocculants. These polymers are particularly effective in a pulp slurry which has a high content of interfering substances and other phenolic compounds.
