General description

Poly(styrene-co-divinylbenzene) are crosslinked microspheres composed of various concentrations of divinylbenzene from 5 to 75mol% based on styrene monomer.[1] The gel-type PS beads are used as carrier to encapsulate metallocene catalysts.[2]

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

Questions

1–2 of 2 Questions  

  1. What is the maximum mass (in Da) that can be separated using Poly(styrene-co-divinylbenzene) microspheres with an average particle size of 6.0-10.0 μm in size exclusion chromatography?

    1 answer

    1. With an average pore diameter of 60 Å, it is estimated that the maximum mass that could be separated using this material would be 1000 Da.

      Helpful?

  2. How was surface area determined for this material?

    1 answer

    1. The nominal "500 m2/g" surface area value for Product No. 468312 is based on supplier information, but only the average particle size is tested and reported on a batch-to-batch basis. An electrical sensing zone particle size analyzer is used for this purpose.
