A method for the preparation of stable emulsions of polyelectrolyte with a high molecular weight in the reverse emulsion

摘要

Process for the preparation of stable emulsions of polyelectrolytes of high molecular weight in the inverse emulsion -, in which: & br / is dissolved the monomers in an aqueous phase, & br / an organic phase is prepared containing a surfactant, & br / . these two phases in order to obtain an emulsion of the water-in-oil type (e / h), & br / is polymerized the monomers, & br / . it incorporates the emulsion in order to obtain a water-in-oil emulsion (e / h), so as to make the polyacrylamide obtained is soluble in water; br / characterized in that it consists in adding to the aqueous phase, a soluble polymer of low molecular weight of the same chemical characteristics and of ionic character that the polyelectrolyte of high molecular weight considered. br / application envisaged: preparation of polyacrylamide for the applications of flocculation and / or thickening (treatment of municipal water and industry, paper).
