4,4′-(Hexafluoroisopropylidene) diphthalic anhydride is involved in the synthesis of polyamides derived from terphenylenes, which is used for gas separation.
4,4′-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) can be used:
(1) With APAF as dianhydride monomer, it can be used to prepare thermally rearranged polybenzoxazole (TR-PBO) gas separation membranes by thermal rearrangement reaction at 450°C. The product TR-PBO membrane has excellent gas permeation selectivity and high permeability. the H2/CH4 separation performance of APAF-6FDA membrane is close to the Robertson upper limit of 2008 [5].
(2) Used as a raw material for the preparation of thermoplastic fluorinated polyimide resin.[6].
(3) Polymers for electronic materials;
(4) Polyimide materials. These materials can be used as substrates for wearable devices and as multilayer insulation materials in order to protect against space dust, cosmic rays and satellite debris[7].
