应用

Clear, colorless fluid polymer useful as a stationary phase in gas chromatography and as an anti-foaming agent.
Dimethylpolysiloxane is used in protein chromatography and affininty chromatography. Dimethylpolysiloxane was used to determine that postprandial inflammatory response after ingestion of heated oils in obese persons is reduced by the presence of phenol compounds.

Questions

  1. What is the molecular weight of this polymer? is it soluble in toluene or THF? Thanks

    1 answer

    1. The molecular weight of this polymer is ~28,000, as mentioned in the "Properties" section of the product detail page. This material is not soluble in toluene or tetrahydrofuran, however a study found this material to be soluble in chloroform, ether, and xylene.

      To review the study please see this journal article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3146108/
