Abstract
PIMs are a class of ultra-permeable polymer that are attracting attention for membrane applications [1]. Here we describe the synthesis and properties of new polyimides designed according to the concept of PIMs in that they possess highly rigid and contorted structures (Fig. 1). These PIM-PIs were prepared using a novel aromatic bisanhydride monomer together with commercial aromatic diamines known to be compatible with obtaining polyimides of high gas permeability. These new polymers will be compared to previously published PIM-PIs of high permeability [2]. Figure 1. An example of a novel PIM-PI.
