Abstract: Linear basic polymers containing, as characteristic components, from 90 to 10 mole % of copolymerized units of the formula and from 10 to 90 mole % of copolymerized units of the formula are obtained by polymerizing the compound of the formula CH2=CH-NH-CHO (N-vinylformamide) to a polyvinylformamide in the presence of a free radical polymerization initiator and splitting off the formyl group from the resulting polymer at from 20 DEG to 200 DEG in the presence of an acid or base. The reaction products are used as retention agents, drainage assistants and flocculants in papermaking.

Abstract: Reaction products of hydrogen cyanide are prepared by a process in which hydrogen cyanide prepared in a conventional manner by pyrolysis at from 250 DEG to 650 DEG C. over a solid under from 5 to 200 mbar is cooled to a temperature of from 200 DEG to -10 DEG C. together with the other pyrolysis products, the hydrogen cyanide is then fed to a chemisorption reaction with a base or with a carbonyl compound, and the reaction products of hydrogen cyanide which are formed therein are removed from the system and brought to atmospheric pressure. In this process, the handling of large amounts of hydrogen cyanide is avoided.
