WebDec 1, 2006 · We are developing new types of polymer – termed polymers of intrinsic microporosity (PIMs) – which in the solid state behave like molecular sieves. As … WebPolymers of intrinsic microporosity, or PIMs, are characterized by rigid and nonlinear or nonplanar backbones that inhibit space efficient packing, thus creating microporosity. …

WebThe gas permeation parameters (permeability (P), diffusion (D) and solubility (S) coefficients) were determined for these polymers. These PIM-PIs exhibit both high apparent surface areas and high gas permeability coefficients, greater than those of most polyimides studied so far and only slightly smaller than the permeability coefficients of the archetypal … WebInstitute for International Co-operation.
