摘要
Membranes with high permeability to gases are formed from polyimides with rigid backbones that incorporate a spiro-centre (see figure). A route to this new range of high-free-volume polyimides is demonstrated, and exceptional performance is obtained for a polymer containing a dimethyl binaphthyl unit.
