Process For Preparation Of Aqueous Solutions Of Water-Soluble Polymers
US Patent:
4358550, Nov 9, 1982
Filed:
Jul 14, 1981
Appl. No.:
6/283243
Inventors:
Louis Jacono - Newark DE
Thomas O. Mumper - Wilmington DE
Thomas O. Mumper - Wilmington DE
Assignee:
Hercules Incorporated - Wilmington DE
International Classification:
C08L10100
US Classification:
523348
Abstract:
An improved process is provided for rapidly dissolving water-soluble polymer gels in which the gels are subjected to the steps of extrusion, cutting of the extruded gels, forming a slurry of gel particles, subjecting the slurry to high shear forces, and finally mixing the resulting slurry and water to form a dilute aqueous solution of polymer. The improvement comprises cutting of the water-soluble polymer gel, prior to extrusion, into pieces of gel of a size which are small enough to fit into space defined between adjacent flights of the extruder at the feed inlet of the extruder. The process enables dilute aqueous solutions to be prepared on a batch or continuous basis with good reproducibility of polymer concentration in the solution being prepared.
