Optimization of the polycondensation reaction was made to obtain high molecular weight products when using DF, which has not previously been used for linear polymer synthesis. Due to the absence of chemically labile units, these polymers exhibited excellent chemical and thermal stability. Linear SEAr polymers were blended with porous polymer networks derived from IS and MeIS, and both neat/mixed materials were tested as membranes for gas separation. The gas separation properties of both pristine polymers and mixed matrix membranes were good, showing some polymer membrane CO2 permeability values higher than 200 barrer. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ © 2023 The authors Atribución 4.0 Internacional Polymers Polimeros y polimerización Porous materials Strength of materials Resistencia de los materiales Gases - Separation Polymer materials derived from the SEAr reaction for gas separation applications info:eu-repo/semantics/article
