Abstract: Graft polymers obtainable by the radically initiated polymerisation of (A) monomers or monomer mixture of (a) 1 to 100 wt.% N-vinyl carboxylic acid amides of the formula (I) in which R1, R2 = H and C1 to C6 alkyl, (b) 0 to 99 wt.% other monoethylenically unsaturated monomers copolymerisable with the monomers (a), and (c) 0 to 5 wt.% of at least two ethylenically unsaturated monomers with unconjugated double bonds in the molecule; in the presence of (B) polymers containing units of vinyl esters of saturated C1 to C4 carboxylic acids and/or vinyl alcohol units, or mixtures containing these polymers and polymers containing at least 3 alkylene oxide units or polytetrahydrofurane; in the ratio by weight (A) : (B) of (95 to 10) : (5 to 90), possibly followed by the separation of the group (II) from the polymerised monomers (I) of the graft polymer, with the formation of units of the formula (III); process for the production of the graft polymers and use of the graft polymers described above in the production of paper, paperboard and cardboard as a dry and wet strengthening agent, as a retention and dewatering agent and as a promoter in diketene gumming and as a starch cationisation agent, as a dispersant for pigments and as a creping auxiliary in the production of tissue papers.

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.
