| titleOfInvention | Water-in-oil polymer dispersions with polymeric emulsifier |
| abstract | Abstract of the Disclosure The Specification describes novel polymer dispersion comprising a dispersion in a continuous organic phase which is not completely miscible with water, of a fine particle size aqueous phase comprising a water-soluble high-molecular weight polymer dissolved in water or swelled with water, the disper-sion containing a water-soluble acid and a water-in-oil emulsifying agent sol-uble in the organic phase and comprising (a) a vinyl polymer of (i.) 10 to 50% by weight of at least one vinyl monomer containing a basic nitrogen atom, (ii) 90 to 50% by weight of at least one vinyl monomer containing a side chain comprising an alkyl group of at least 6 carbon atoms, or a mixture of at least one such monomer with a minor amount of one or more further non-water-soluble. vinyl monomers, and, if desired (b) one or more other surface-active compounds whereby the resulting HLB value of the complete emulsifying agent is below 6 at a pH value above 4, and above 8 at a pH value below 2. The above dispersions can be used to prepare aqueous solutions of the water-soluble polymer by admix-ing the dispersion with an excess of water, the acid in the dispersion serving to neutralise the basic nitrogen atoms of the vinyl polymer contained in the dispersion. Such dispersions render the polymer more quickly and completely soluble in water. |
