    • A high molecular weight, water-soluble polymer, water-in-oil emulsions thereof and a flocculating process using same are disclosed. The polymer may be represented by the formula: ##STR1## wherein A represents a repeating unit derived from a hydrophobic vinyl monomer having a water-solubility of less than about 5 weight %; R.sub.1 and R.sub.3 are each hydrogen atom or a methyl group; R.sub.4 and R.sub.5 are each a hydrogen atom, a methyl group or an ethyl group; R.sub.2 represents a divalent hydrocarbon group having from 2 to 13 carbon atoms; X represents a monovalent cation; B represents a repeating unit derived from an ethylenically-unsaturated carboxylic acid or a salt thereof; m is about 0.1-10 mole %, n is about 1-40 mole %, p is about 20-98.9 mole %, and q is about 0-40 mole % with the proviso that m+n+p+q=100 mole % and r is a large positive integer.
