Crosslinked thermally rearranged poly(benzoxazole-co-imide), gas separation membranes comprising the same and preparation method thereof |
| abstract |
Provided is a crosslinked thermally rearranged poly(benzoxazole-co-imide) obtained through the transesterification crosslinking of an ortho-hydroxy polyimide copolymer and a diol compound, followed by thermal rearrangement, a gas separation membrane (excluding a membrane for flue gas separation), and a method for preparing the same. The crosslinked thermally rearranged poly(benzoxazole-co-imide) according to the present invention allows less packing of polymer chains and has a structure with a larger space, and thus shows increased possibility of permeation and diffusion of small molecules therethrough. In addition, the gas separation membrane (with the proviso that a membrane for use in flue gas separation is excluded) including the crosslinked thermally rearranged poly(benzoxazole-co-imide) according to the present invention has excellent gas permeability and selectivity, and particularly shows gas separation quality in terms of carbon dioxide/methane separation corresponding to a level exceeding the so-called 2008 upper bound. |
