GAS PERMEATION OF AMINE-CROSSLINKED POLY(2,6-DIMETHYLPHENYLENE OXIDE) MEMSRANE
Abstract:
Poly(2,6-dimethylphenylene oxide) (PFO) has been brominated and crosslinked with ammonia, ethylenediamine, m-phenylenediamine and hexamethylenetetramine. It was found that the oxygen permeability of the polymer membrane increased with the aryl-bromine con-tent in BrPPO and decreased with the benzyl-bromine content in BrPPO. NH3-crosslinking of BrPPO increased the oxygen permeability. Ethylenediamine-crosslinking of BrPPO increased the selectivity of oxygen over nitrogen significantly. Through crosslinking of benzyl-bromi-nated PPO a solvent resistant membrane with high selectivity of oxygen over nitrogen was obtained.
