Atom transfer radical polymerization of methyl acrylate with molybdenum halides as catalysts in an ionic liquid
Résumé
The atom transfer radical polymerization of methyl acrylate in 1‐butyl‐3‐methylimidazolium hexafluorophosphate was studied with a molybdenum halide catalytic system. A combination of a bromine‐containing initiator (ethyl‐2‐bromopropionate) with a chloride‐containing catalyst [MoCl3(PMe3)3/MoCl4(PMe3)3] led to a controlled polymerization, and matrix‐assisted laser desorption/ionization time‐of‐flight analysis of the polymers indicated that the reversibly deactivated macromolecules contained both bromine and chloride end groups.
