Synthesis and Characterization of High Performance Polymers for Gas Separation Membranes
… small difference between meta- and para-oriented polyhydroxyimides in permeability coefficients was observed. The TR polybenzoxazoles derived from meta/para-oriented isomeric polyimides with ortho functionality had similar gas separation properties, especially for CO2/CH4 separation, and it is …

Synthesis and Characterization of Toughened Thermally Rearranged Polymers, Poly(2,6-Dimethylphenylene-oxide) Based Copolymers and Polymer Blends for Gas Separation Membranes
Thermally rearranged (TR) polymers have outstanding gas separation properties, but are limited in their industrial application due to being mechanically brittle. A series of low volume fraction of a poly(arylene ether sulfone) (PAES) block was introduced into the TR precursor polyhydroxyimide (PI) …
