Abstract:
High free-volume copolymers were prepared via polycondensation with 2; 3,5; 6,-tetrafluoroterephthalonitrile (TFTPN) in which a portion of the 3; 3,3',3'-tetramethyl- 1; 1'-spirobisindane (TTSBI) of PIM-1 was replaced with dibutyl anthracene maleimide (4bIII). An investigation of free volume using positron annihilation lifetime spectroscopy (PALS), and gas permeation measurements was carried out for the thin film composite copolymer membranes and compared to PIM-1. The average free volume ho... »
