Abstract:
A method for preparing a pourable concentrated polymer/emulsifying surfactant/hydrophobic liquid composition from a starting dehydrated polymer/emulsifying surfactant/hydrophobic liquid composition, which method consists essentially of removing some portion of hydrophobic liquid from said starting dehydrated polymer/emulsifying surfactant/hydrophobic liquid composition in a first centrifuge, thereby producing a pourable concentrated polymer/emulsifying surfactant/hydrophobic liquid composition and a first centrifuge raffinate; wherein said polymer is a water soluble polymer prepared from one or more ethylenically unsaturated monomers and wherein said pourable concentrated polymer/emulsifying surfactant/hydrophobic liquid composition contains less than about 5%, by weight, water and greater than about 60%, by weight, polymer solids.
