Abstract:
A method for recovery of polymer, comprising contacting a polarizing plate comprising a polarizing element and first and second polymer films on its both surfaces, with at least an aqueous liquid, and then applying shear force to the polarizing plate to thereby separate the polarizing element and at least the first polymer film, is disclosed.
