TITLE METHOD FOR DISSOLVING POLYMERS IN COMPATIBLE LIQUIDS AND USES THEREOF INVENTOR William WEITZEN ABSTRACT This invention provides a technique for extremely rapid dissolution, or dispersion on essentially the molecular level, of certain polymeric materials in compatible liquid vehicles. The polymeric materials are comminuted at cryogenic temperatures and are then introduced into a liquid vehicle preferably while still at or near cryogenic temperature. At low concentrations, the resulting blend or system displays reduced friction to flow while high concentrations may be used to immobilize the liquid vehicle and/or reduce its vapor pressure.
