    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： Chlorofluorocarbon-free, urethane-containing moldings having a cellular core and an integral skin with an essentially pore-free surface, ie. polyurethane (PU) integral foams, are produced by reacting the conventional starting components in the presence of blowing agents, catalysts and at least one additive selected from the group consisting of the partially or completely neutralized (1) homopolymers of monoethylenically unsaturated monocarboxylic acids, dicarboxylic acids or the internal anhydrides thereof, (2) copolymers of (2i) monoethylenically unsaturated monocarboxylic acids, dicarboxylic acids or the internal anhydrides thereof and (2ii) carboxyl-free, monoethylenically unsaturated monomers copolymerizable with (2i) and (3) copolymers or graft copolymers of (3i) monoethylenically unsaturated monocarboxylic acids and/or their salts,(3ii) monoethylenically unsaturated dicarboxylic acids, their salts and/or their internal anhydrides and (3iii) if required, carboxyl-free, monoethylenically unsaturated monomers copolymerizable with (3i) and (3ii) in a closed mold with compaction.
