SiliaMetS Thiol in the Synthesis of Polymer Films for Measurement of Optical Properties

> back to SiliaMetS Case Studies

An asymmetric bifunctional monomer having both an unprotected alkynyl group and a vinyl ether (VE) polymerization of VEEP smoothly proceeded in a controlled manner under a living cationic polymerization condition to give alkyne-substituted polyVE (poly-VEEP) without any protection of the pendant alkynyl function.

In the click reaction of precursor macromonomer MA-PVEEP (scheme), the resultant polymer MA-P(VE-Mal) was purified from contaminating copper with SiliaMetS Imidazole.

    SiliaMetS Imidazole (IMI) (R79230B)

    SiliaMetS Imidazole (Si-IMI) is a versatile metal scavenger for a variety of metals including Cd, Co, Cu, Fe, Ni, Pd, and Rh under a wide range of conditions and the preferred metal scavenger for iron catalysts. It can also be used as an amine base in systems that are generally sensitive to basic conditions compared to other SiliaMetS supported bases.
