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 under a wide range of conditions and the preferred metal scavenger for iron catalysts. Best scavenger for: Cd, Co, Cu, Fe, Ir, Li, Mg, Ni, Os, W & Zn. Good scavenger for: Cr, Pd & Rh. It can also be used as an amine base in systems that are generally sensitive to basic conditions compared to other SiliaMetS supported bases.
