Glass or rubbery polymer that includes a large number of macropores
(
–
in diameter) that persist when the polymer is immersed in solvents or in the dry state.
Notes:
- Macroporous polymers are often network 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-exclusion chromatography columns.
- Porous polymers with pore diameters from ca
to
are called mesoporous polymers.
