ABSTRACT:
An apparatus for the preparation of polymer solutions contains a stirring device, a cooling device connected to the stirring device and a warming device connected to the cooling device. Both the warming device and the cooling device are characterized by including a rotary screw. The stirring device functions to mix a polymer with a solvent to produce a swelled polymer in the solvent. The incorporation of a screw into the warming or cooling device allows the temperature of the solution to change while simultaneous mixing and shear is provided.
