Date Oct. 12, 1995Solutions of polymers containing vinylamine units, which solutions have a long shelf life, are prepared by hydrolyzing polymers containing N-vinylcarboxamide units with acids in an aqueous medium and removing the carboxylic acids eliminated from the polymers as esters from the aqueous polymer solution after the hydrolysis by adding at least stoichiometric amounts of at least one C1-C6-alcohol and distilling off the esters from the reaction mixture, and said aqueous solutions are used as dry and wet strength agents in papermaking.

Abstract: Graft polymers are obtained by radically initiated polymerisation of (A) monomers or monomer mixtures of (a) 10 to 100 % by weight N-vinyl carboxylic acid amides having the formula (I), in which R1 stands for R2=H and C1-C6 alkyl, (b) 0 to 90 % by weight other monoethylenically unsaturated monomers that may be copolymerised with monomers (a), and (c) 0 to 5 % by weight of at least two ethylenically unsaturated monomers that contain non-conjugated double bonds in their molecule, in the presence of (B) polymers that contain at least 3 units of a C2-C4 alkylene oxide and/or polytetrahydrofuranes, in a weight ratio (A):(B) equal to (95 to 10):(5 to 80). The group (IV) is then optionally separated from the polymerised monomer (a) of the graft polymer, forming at least units having the formula (1). Also disclosed are a process for preparing said graft polymers and their use as dry and wet strengthincreasing agents, as fixatives for impurities and fillers, as retention and dewatering agents for paper-making, as promoters during paper, cardboard and paperboard diketen gluing, as pigment dispersants, as starch cationising agents and as auxiliary substances for producing paper tissues.
