Continuous solution method

摘要

A method is disclosed for preparing a homogeneous solution of a powder, particularly hard-to-wet polymer powders, which includes: (1) feeding simultaneously a powder and a liquid solvent for the powder to a high-speed in-line mixer minimizing contact between said powder and said liquid solvent before said powder and said liquid solvent enter said mixer; (2) mixing said powder and said liquid solvent in said mixer to form a dispersion of said powder in said liquid solvent; and (3) dissolving said dispersed powder in said solvent.
