Abstract
The invention features dilute solutions of rigid rod or extended rod lyotropic liquid crystalline polymers prepared from high concentration polymerization mixtures. The invention also features methods of preparing such dilute solutions which utilize high mechanical shear to induce mix the high concentration solution with a diluent. The invention further provides articles of manufacture, including films and fibers, having a porous microstructure which are prepared from the dilute homogeneous solutions of the invention.
