摘要： Rapidly dissolving/absorbing free-flowing powders of hydrophilic/superabsorbent (co)polymers, having irregular nonspherical morphology and a particle size distribution ranging from 100 .mu.m to 800 .mu.m, are prepared by (a) phase inversion (co)polymerizing stirred admixture of (i) a hydrocarbonic solution of at least one surfactant having an HBL ranging from 8 to 12 and (ii) an aqueous solution of at least one hydrophilic unsaturated monomer, in the presence of an effective amount of a radical polymerization initiator and at a predetermined temperature of (co)polymerization, (b) next introducing into the medium of (co)polymerization, after (co)polymerization of the at least one hydrophilic unsaturated monomer, a second aqueous solution of at least one hydrophilic unsaturated monomer, (c) then (co)polymerizing the second aqueous solution, and (d) thence extracting the hydrocarbonic phase and water from the resulting (co)polymerizate and drying same, with the proviso (e) that the second aqueous monomer solution is introduced at a temperature of about the predetermined temperature of (co)polymerization and the volumetric ratio of aqueous phase to hydrocarbonic phase ranges from 0.6 to 1.2.

摘要： The process consists in the agglomeration of fine particles of superabsorbent polymer, carried out by introducing an aqueous solution of monomer into a slurry of aqueous polymer dispersed within a hydrocarbon liquid, this introduction being performed directly at the temperature and in conditions of polymerization of the monomer. A superabsorbent product is thus obtained in a very good yield, in the form of aggregates of particles such that the fraction passing through a 100-micron screen is less than 1%.
