Abstract: Synthesis of poly‐m‐phenylene isophthalamide (PMIA) solutions via polycondensation inherently generates HCl as a by‐product, adversely affecting polymer stability and necessitating neutralization. Introducing neutralizers adds water, a non‐solvent for PMIA, and cosolvent salts into the solution.… read more here.
