Appeal No. 1997-1604
Application No. 08/273,688
surfactant/hydrophobic liquid composition, which method
comprises: a) 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; and b) centrifuging said
first centrifuge raffinate in a second centrifuge to capture
additional polymer solids.
18. A viscous, pourable polymer emulsifying
surfactant/hydrophobic liquid composition having a viscosity
of about 300 cps to 25,000 cps and containing greater than
about 60% polymer solids and less than about 5% water prepared
by centrifuging a starting dehydrated polymer/emulsifying
surfactant/hydrophobic liquid composition, wherein said
polymer is a water soluble polymer prepared from one or more
ethlenically unsaturated monomers.
