Document Type and Number:
WIPO Patent Application WO/2016/002785
Kind Code:
A1
Abstract:
Provided is a method for manufacturing an aromatic polymer, suitable for manufacturing a separator for a nonaqueous-electrolyte secondary cell in which a high degree of safety can be ensured. A method for manufacturing an aromatic polymer having a structure represented by the formula –C(=)NH-, comprising reacting, in an organic solvent, an aromatic diamine and a compound having a hydrolyzable reactive group for reacting with an amino group, the organic solvent containing 200 ppm-2500 ppm of water, and the intrinsic viscosity of the aromatic polymer being 1.5 dL/g-3.0 dL/g.
