Abstract: In a process for making paper, paperboard and cardboard, paper pulps containing interfering materials are dehydrated in the presence of polymers which, as characteristic constituents, contain copolymerised units of the formulae … … with R and R = H or C1- to C3-alkyl, and have K values of at least 130, the polymers containing less than 10 mol% of units of formula II.

Date Oct. 4, 1990.Paper, board and cardboard are produced by draining a paper stock in the presence of a nonhydrolyzed copolymer which contains, as polymerized units, (a) from 99 to 1 mol % of N-vinylformamide and (b) from 1 to 99 mol % of one or more water-soluble basic monomers of the formula (I) or (II) where R1 is H, CH3 or C2H5, R2, R3 and R4 are each H, CH3, C2H5 or (-CH2-CH2-O-)nH, R5 and R6 are each C1-C10-alkyl, A is C1-C6-alkylene, n is from 1 to 6 and Y(-) is an anion, in an amount of from 0.01 to 3.5% by weight, based on dry paper stock.
