Glass or rubbery polymer that includes a large number of macropores (\(50\ \text{nm}\)–\(1\ \unicode[Times]{x3BC}\text{m}\) 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 \(50\ \text{nm}\) are called mesoporous polymers.
