Description

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
• as adsorbent
• as matting agent for coatings, anti-blocking and lubrication additive for films and filler for ceramics, cosmetics and dental materials
