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.

Abstract: Novel alpha -iminodiacetonitriles are prepared by a process in which an aldehyde-cyanohydrin or a haloacetonitrile is reacted with an aminonitrile, the reaction being carried out in the presence of a lower alkanol in the case of the preparation of symmetric alpha -iminodiacetonitriles, and in the presence of an auxiliary base in the case of the preparation employing a haloacetonitrile. The alpha -iminodiacetonitriles obtainable by the process of the invention are useful starting materials for the preparation of dyes, fungicides, bactericides, herbicides, textile assistants, anticorrosion agents, complex-forming agents, stabilizers in electroplating baths and inhibitors for antifreezes.

Abstract: A process for producing long-shelf-life aqueous solutions of vinyl-amine-unit-containing polymers by the hydrolysis of N-vinyl-carbonamide-containing polymers with acids in an aqueous medium and removing the carboxylic acids separated from the polymers as esters from the aqueous polymer solution following hydrolysis and by the addition of at least stoichiometric quantities of at least one C1 to C6 alcohol and distilling the esters off from the reaction mixture. The invention also relates to the use of the long-shelf-life aqueous solutions of vinyl-amine-unit-containing polymers as dry and wet consolidating agents in paper manufacture.
