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 R stands for R 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 strength-increasing 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.

Abstract: The invention concerns agglomerated polymer particles made from water-expandable polymers and with a mean particle diameter of 20-5000 mu m. The agglomerated polymer particles consist of primary particles with a mean particle diameter of 0.1-15 mu m and can be produced by polymerisation of water-soluble monomers in the presence of a regulator (1-10 wt % in relation to the monomers) and of a cross linking agent (at least 2000 ppm in relation to the monomers), the process being a water-in-oil polymerisation, with subsequent azeotropic de-watering of the water-in-oil polymer emulsion containing the primary particles in the presence of agglomerating polyalkylene glycols which (a) can be obtained by addition fixation of C2-C4 alkylene oxides to alcohols, phenols, amines or carboxylic acids and (b) contain at least two alkylene oxide units incorporated by polymerisation. The agglomerated polymer particles break down into the primary particles when introduced into water. The invention also concerns processes for producing the agglomerated polymer particles and the use of said particles as thickening agents for printing pastes.
