A polymer with a rigid, randomly contorted molecular structure (see Figure), incorporating fused rings connected by spiro‐centres, may be precipitated or cast from solution to give microporous powders and membranes stable up to temperatures of 350 °C, with apparent surface areas > 600 m 2 g –1 . Organophilic membranes may be formed, as demonstrated by the separation of phenol from water by pervaporation.
