Two series of novel aromatic polyimides (PIs) containing three polymers each one were prepared using two new aromatic silylated-diamine monomers. These monomeric diamines contain biphenylsilane units and biphenyl moieties in their structures. All PIs

By removing anhydride groups from crosslinked copolyimide membranes at 430 °C, partially pyrolysed membranes were obtained and gas separation properties were evaluated and related to the content of labile groups. The spaces occupied by the linking a

The work presents an approach to reduce the plasticization of polymeric membranes caused by condensable gases, and particularly the effect of plasticization caused on polyimides by CO2 at high pressure. A technical polyimide, Matrimid®, was chosen a

Two novel copolyimides bearing bulky pendent groups have been prepared by chemical modification of a copolyimide precursor containing carboxylic acid groups. The incorporation of the bulky groups was achieved by esterification of the copolyimide cont
