Popis: Studies of blends of topologically distinct samples of the polymer of intrinsic microporosity PIM-1 demonstrate, for the CO2/N2 gas pair, the ability to vary dramatically the selectivity and aging behaviour of thin film composite (TFC) membranes. Polymerizations carried out in the absence of nitrogen gas produced polymers with higher degrees of branching, which formed further into loops and at higher temperatures into significant amounts of colloidal network PIM-1 (
