Abstract
Provided is a method for preparing a membrane for flue gas separation including a crosslinked thermally rearranged poly(benzoxazole-co-imide) through the transesterification crosslinking of an ortho-hydroxy polyimide copolymer and a diol compound, followed by thermal rearrangement. The membrane for flue gas separation including the crosslinked thermally rearranged poly(benzoxazole-co-imide) has excellent gas permeability and selectivity, and particularly provides gas separation quality corresponding to a level exceeding the so-called 2008 upper bound in terms of carbon dioxide/methane separation.
