General description

Poly(styrene-co-divinylbenzene) are crosslinked microspheres composed of various concentrations of divinylbenzene from 5 to 75mol% based on styrene monomer. The gel-type PS beads are used as carrier to encapsulate metallocene catalysts.

Application

Poly(styrene-co-divinylbenzene) may be used in separation media for TLC, paper and LPL chromatography and may also be used as adsorbent.

Rhodamine absorbed to protein was removed from rhodamine-conjugated antibody solutions by adsorption to hydrophobic macroporous beads (Bio-Beads SM-2) following gel permeation chromatography. This simple technique eliminated the contaminating free dye more effectively than gel filtration alone, but neither significantly reduced
