Glass or rubbery polymer that includes a large number of macropores (50 nm–1 µm in diameter) that persist when the polymer is immersed in solvents or in the dry state.
Notes: - Macroporous polymers are often @NT07562@ polymers produced in bead form. However, linear polymers can also be prepared in the form of macroporous polymer beads.
- Macroporous polymers swell only slightly in solvents.
- Macroporous polymers are used, for example, as precursors for ion-exchange polymers, as adsorbents, as supports for catalysts or reagents, and as stationary phases in size-@E02261@ columns.
- Porous polymers with pore diameters from ca 2 to 50 nm are called mesoporous polymers.
