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.

Date Sep. 28, 1995Graft polymers which contain N-vinyl units and in which the grafting base is a polymer which contains in each case at least 5% by weight of units of the formulae (I) (II) where R1 and R2 are each H or C1-C6-alkyl, monoethylenically unsaturated monomers are grafted onto the grafting base in a weight ratio of from 100:1 to 1:100, and which have K values of at least 7 (determined according to H. Fikentscher in 5% strength by weight aqueous solution at 25 DEG C. and pH 7), are prepared by polymerization of monoethylenically unsaturated monomers in the presence of polymers which in each case contain at least 5% by weight of units of the formulae I and/or II as the grafting base in a weight ratio of from 100:1 to 1:100, and are used as dispersants for pigments, as additives for detergents and cleaning agents, and strength agents for paper and as soil stabilizers and for fertilizer compaction.

Abstract: The invention concerns a method for the elimination of impurities containing cyanide groups from polymers containing acyclic N-vinyl carboxylic acid amide units and/or vinylamine units by treating the polymer with at least one oxidising agent (a) under the action of light and/or (b) in the presence of heavy-metal ions.

Abstract: Graft polymers are obtainable by free radical polymerization of (A) monomers or monomer mixtures comprising (a) from 10 to 100% by weight of N-vinylcarboxamides of the formula (see formula I), where R1 and R2 are each H or C1-C6-alkyl, (b) from 0 to 90% by weight of other monoethylenically unsaturated monomers copolymerizable with the monomers (a) and (c) from 0 to 5% by weight of monomers having at least two ethylenically unsaturated, nonconjugated double bonds in the molecule in the presence of (B) polymers which contain at least 3 units of a C2-C4-alkylene oxide, and/or polytetrahydrofurans, in a weight ratio (A) : (B) of (95 to 10) : (5 to 90) , and, if required, subsequent elimination of some or all of the groups (see formula II) from the polymerized monomers (a) of the graft polymer with formation of units of the formula (see formula III) The graft polymers can be used as dry and wet strength agents, as fixing agents fear interfering substances and fillers, as retention aids and drainage aids in the production of paper and as promoters in the diketene sizing of paper, board and cardboard, as dispersants for pigments, as starch cationizing agents and as assistants in the production of tissue papers.

Abstract: Starch is cationically modified by reacting starch with polymers which contain amino and/or ammonium groups in an aqueous medium at from 115 to 180.degree.C under superatmospheric pressure in the absence of oxidizing agents, polymerization initiators and alkali, by a process in which the reaction is carried out in a manner such that a reduction in molecular weight occurs in not more than 10% by weight of the starch, and the reaction products thus obtainable are used as dry strength agents for paper.
