ABSTRACT:
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%.
