Slurry mixture forming an additive for producing a hydrodynamic drag reduction aqueous polymer solution

摘要

A slurry mixture comprising a water soluble resin of the polyacrylamide class of polymers suspended as a gel in a non-solvent to the resin, but itself water soluble, from a group consisting of (a) the glycol ether type of compounds, or (b) the Tris (tetrahydrofurfuryl) phosphate type containing the tetrahydrofurfuryl ring.
