Polymers of intrinsic microporosity
WebThe resulting polymer was structurally characterized and proven permanently porous with a surface area of 305 m2 g−1. The high concentration of amines (–NH– and –NH2) within the backbone of the polymer result in exceptional selectivity (141) for CO2 over N2 and dynamic capacity (15.1 cm3 g−1) in the presence of water (20 : 80 v/v CO2 : N2, 91% relative … WebJun 1, 2024 · A detailed investigation has been carried out of the pre-polymerisation modification of the polymer of intrinsic microporosity PIM-1 by the addition of two methyl …
