| titleOfInvention | Process for the manufacture of stable water-oil emulsions of hydrolysed N-vinyl amide polymers, and use thereof |
| abstract | Process for preparing stable water-in-oil emulsions of hydrolysed polymers of N-vinylamides of the formula n<IMAGE>n in which R and R<1> denote H or C1-C6-alkyl, by polymerising compounds of the formula I, alone or mixed with other monoethylenically unsaturated monomers, in the form of water-in-oil emulsions to give water-in-oil polymer emulsions, and subsequently hydrolysing the polymers, the hydrolysis of the polymers in the form of water-in-oil polymer emulsions being carried out in the presence of acids or bases and from 1 to 30% by weight, based on the polymers, of emulsifiers which are obtainable by reactingn (A) C10- to C22-fatty alcohols with epichlorohydrin in the molar ratio 1:0.5 to 1:1.5 to give glycidyl ethers,n (B) reacting the glycidyl ethers with (1) saturated C2- to C6-alcohols containing 2 to 6 OH groups or (2) monoethers thereof with C10- to C22-fatty alcohols, in the glycidyl ether:(1) or (2) molar ratio of from 1:0.5 to 6, in the presence of acids or bases, andn (C) alkoxylating the reaction products from (B) using at least one C2- to C4-alkylene oxide in the molar ratio 1:1 to 6. n<??>The polymer emulsions obtainable in this way are used as dewatering, retention and flocculating agents in the production of paper and paper products. |
