Abstract
A mixing apparatus for continuously generating a homogeneous mixture of a polymer and a less viscous fluid is provided. The mixer includes means for continuously injecting a viscous polymer into a pressure vessel; means for continuously injecting a lower viscosity fluid into the pressure vessel; means for continuously injecting a plasticizing agent into the viscous polymer entering the pressure vessel; high shear centrifugal mixing means within the pressure vessel for mixing the polymer and the less viscous fluid; drive means for rotating the rotational mixing means; heating means for maintaining the temperature of the substances being mixed in the pressure vessel at a desired mixing temperature; and means for continuously discharging a homogeneous mixture of the polymer, the plasticizing agent, and the less viscous fluid from the mixer.
