Gas transport properties of new aromatic cardo poly(aryl ether ketone)s

Polymeric membranes for the hydrogen economy: Contemporary approaches and prospects for the future

“…Camacho-Zuniga et al [56] synthesized a series of cardo poly(aryl ether ketone)s with side phthalide groups and aryl ether ketones of varying lengths. An improvement in H 2 /CO 2 selectivity was obtained by increasing the length of aryl ether ketone in the polymer backbone.…”

Synthesis, properties, and gas permeation performance of cardo poly(arylene ether sulfone)s containing phthalimide side groups

“…[2][3][4] The term ''cardo polymers'' refers to polymers containing bulky side groups. 5 It has been known that the introduction of cardo groups along the polymer backbone disrupts crystallinity, increases their glass transition temperature, and improves their solubility. For example, phenolphthalein-based cardo poly(aryl ether sulfone) (PES-C) has been noted for its excellent solubility, mechanical toughness, thermoxidative stability, and high glass transition temperature.…”

Fluorinated poly(arylene ether)s with aliphatic chain appended cardo moiety: Synthesis and gas transport properties

“…A weak acid base interaction between CO 2 and the lone pair of electrons on fluorine in a C-F bond may be a possible reason for higher solubility coffecient values [40,41]. Thus, the higher permeability of CO 2 compared to other gases in this study is due to its high solubility coefficients in these PAEs [42,43].…”
