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.

DOI: 10.1063/5.0002336
Abstract: This study analyzes the mechanism of electron loss at the discharge chamber wall of a microwave discharge neutralizer via three-dimensional particle-in-cell simulations with Monte Carlo collisions (PIC–MCCs). The neutralizer employs electron cyclotron resonance discharges with… read more here.
