Abstract: The invention relates to aqueous dispersions of reactive gluing agents containing 0.1 to 10 weight per cent of water-soluble or water-dispersible polymeric protective colloids which can be obtained by reacting polymers containing amino groups from the group: polymers containing vinylamine units; polyamidoamines; polyamidoamines grafted with ethylenimine - with diketenes at a weight ratio polymers:diketenes of 10000:1 to 1:3. The invention also relates to a method for producing aqueous dispersions of reactive gluing agents by homogenising said reactive gluing agents in an aqueous solution of at least one of the aforementioned protective colloids at temperatures of 20 to 90 DEG C under the effect of shear forces, and to the use of aqueous dispersions of gluing agents thus obtained as pulp sizing agents in the production of paper, board and cardboard and for hydrophobing cellulose fibers.

Abstract: Oligomers (I) of open-chain N-vinylcarboxamides of formula CH2=CH-N(R')-C(O)-R (II) and optionally comonomer(s), prepared by cationic polymerisation using a finely-divided inorganic solid (III) with a tertiary halide of formula (R )(R )(R )C-X (IV) adsorbed on its surface, are new; in which R, R' = hydrogen (H) or 1-6 carbon (C) alkyl; R , R , R = 1-15 C alkyl, aryl or methoxyphenyl; X = halogen.

Abstract: The invention concerns insoluble polymers which can swell only slightly and contain units of formula (I) and/or (II), in which R is H, C1-C6 alkyl; R , R are H, C1-C20 alkyl, aryl, aralkyl; and ME is H, alkali metal, alkaline earth metal or ammonium equivalent. The invention also concerns processes for preparing these polymers by reacting insoluble polymers which can only swell slightly and contain units of formula (III), in which R is H or C1-C6 alkyl, with (1) alpha -haloacids or their alkali metal, alkaline earth metal or ammonium salts, or (2) aldehydes and hydrogen cyanide or alkali cyanide, or cyanohydrins comprising aldehydes and alkali cyanide, and hydrolyzing the adducts. The invention further concerns the use of these polymers as adsorber resin for metallic ions and as ion exchangers.
