Suspension of polymer containing a water-soluble polymer in suspension in an oily phase, for its preparation and its use in the preparation of aqueous solutions of polymers diluted

摘要

Of the suspensions of polymers which dissolves rapidly in water in the presence of an acid are formed in accordance with the invention of an organic phase coherent not miscible with water, in all proportions, of a polymer containing water and the state of division in the organic phase, this phase, the polymer containing a water-soluble polymer, if any of an acid and an emulsifying agent macromolecular soluble in the organic phase, this emulsifying agent consisting of a mixture of two copolymers of 10 to 50 of monomers carrying a basic nitrogen atom and 90 to 50 of the monomers has a long chain alkyl lateral, differant them from 0,1 to 1,5points by taking as a basic nitrogen.
