PRODUCTION OF SUPERABSORBENT POLYNER IN FORM OF FLOCCULATE PARTICLE FOR WATER AND WATER-BASE FLUID |
摘要 |
Prepn. of super-absorbent polymer (A) in the form of a powder of agglomerates of spherical particles comprises agglomerating fine (A) particles using as agglomerating agent (B) an aq. soln. (C) of a monomer (I), suspended in a liq. hydrocarbon that is a non-solvent for both (A) and (B). (C) is introduced into the liq. hydrocarbon at the polymerisation temp. of (I); (I) is 50-200 wt.% w.r.t. (A) and (C) also includes a hydrophilic additive, i.e. a thickener (D) and a surfactant (E) of HLB 8 or more. |
