    摘要： Stable water-in-oil emulsions of hydrolyzed polymers of N-vinylamides of the formula ##STR1## where R and R.sup.1 are each H or C.sub.1 -C.sub.6 -alkyl are prepared by polymerization of a compound of the formula I alone or as a mixture with other monoethylenically unsaturated monomers, in the form of a water-in-oil emulsion, to give a water-in-oil polymer emulsion, and subsequent hydrolysis of the polymer, by a process in which hydrolysis of the polymer in the form of the water-in-oil polymer emulsion is carried out in the presence of an acid or base and of from 1 to 30% by weight, based on the polymer, of an emulsifier which is obtainable by(A) reacting a C.sub.10 -C.sub.22 -fatty alcohol with epichlorohydrin in a molar ratio of from 1:0.5 to 1:1.5 to give a glycidyl ether,(B) reacting the glycidyl ether with (1) a saturated C.sub.2 -C.sub.6 -alcohol containing from 2 to 6 OH groups or (2) its monoether with a C.sub.10 -C.sub.22 -fatty alcohol, in a molar ratio of glycidyl ether to (1) or (2) of from 1:0.5 to 1:6, in the presence of an acid or base, and(C) alkoxylating the reaction product from (B) with one or more C.sub.2 -C.sub.4 -alkylene oxides in a molar ratio of from 1:1 to 1:6.The polymer emulsions obtainable in this manner are used as drainage aids, retention aids and flocculants in the making of paper and paper products.

    摘要： N-vinylformamide is polymerized with or without other water-soluble monoethylenically unsaturated monomers and with or without water-insoluble monoethylenically unsaturated monomers in not less than 30% strength by weight aqueous monomer solutions in the presence of a polymerization initiator at not more than 150.degree. C. in a kneader by a method in which the polymerization is carried out to such an extent that the initially formed water-containing polymer gel disintegrates into fine particles and the finely divided polymer obtainable in this manner is hydrolyzed, preferably in the kneader, so that not less than 0.1 mol % of the N-vinylformamide units present in the polymer are converted into vinylamine units. The polymers obtainable in this manner dissolve readily in water. The aqueous solutions are used, for example, in papermaking and tertiary oil production.

    摘要： Cationic urea/formaldehyde resins are obtainable by condensing urea and formaldehyde in a molar ratio of from 1:1.5 to 1:3 in the presence of polymers which contain not less than 1 mol % of polymerized vinylamine units and have Fikentscher K values of from 5 to 300, in an amount of from 5 to 50 g per mole of urea in the end product, where the mixture is first a) precondensed at a pH of from 8 to 14, then acidified and b) condensed at a pH of from 1 to 5 until gel formation begins, c) then from 0.3 to 1.5 moles of formaldehyde are added per mole of urea used, d) post-condensation is carried out and e) the resin solution is subsequently neutralized. The resins thus obtained are used in papermaking as assistants for increasing the dry and wet strength of paper and result in less dulling of the whiteness of the paper.
