Structure and synthesis

Relisorb™ resins are based on a rigid low swelling hydrophilic polymethacrylate polymer characterised by a highly porous structure with an average pore radius of 40 – 50 nm.

Relisorb™ are manufactured by a radical suspension polymerisation followed by the functionalization of the product thus obtained.
During the polymerization, highly porous opaque beads are formed with a calibrated particle size range.

Porogenic agents are able to dissolve the monomers but precipitate the synthesized polymer. The result is a sponge-like structure with free accessible inner surface.
