Abstract
IN THE PRESENT INVENTION HIGH PERFORMANCE CROSS-LINKED POLYBENZOXAZOLE AND POLYBENZOTHIAZOLE POLYMER MEMBRANES AND METHODS FOR MAKING AND USING THESE MEMBRANES HAVE BEEN DEVELOPED. THE CROSS-LINKED POLYBENZOXAZOLE AND POLYBENZOTHIAZOLE POLYMER MEMBRANES ARE PREPARED BY: 1) FIRST SYNTHESIZING POLYIMIDE POLYMERS COMPRISING PENDENT FUNCTIONAL GROUPS (E.G., -OH OR -SH) ORTHO TO THE HETEROCYCLIC IMIDE NITROGEN AND CROSS-LINKABLE FUNCTIONAL GROUPS IN THE POLYMER BACKBONE; 2) FABRICATING POLYIMIDE MEMBRANES FROM THESE POLYMERS; 3) CONVERTING THE POLYIMIDE MEMBRANES TO POLYBENZOXAZOLE OR POLYBENZOTHIAZOLE MEMBRANES BY HEATING UNDER INERT ATMOSPHERE SUCH AS NITROGEN OR VACUUM; AND 4) FINALLY CONVERTING THE MEMBRANES TO HIGH PERFORMANCE CROSS-LINKED POLYBENZOXAZOLE OR POLYBENZOTHIAZOLE MEMBRANES BY A CROSSLINKING TREATMENT, PREFERABLY UV RADIATION. THE MEMBRANES CAN BE FABRICATED INTO ANY CONVENIENT GEOMETRY. THE HIGH PERFORMANCE CROSS-LINKED POLYBENZOXAZOLE AND POLYBENZOTHIAZOLE POLYMER MEMBRANES OF THE PRESENT INVENTION ARE SUITABLE FOR A VARIETY OF LIQUID, GAS, AND VAPOR SEPARATIONS.
