摘要：
Sodium iodide (NaI) and potassium iodide (KI) were utilized as efficient catalysts for living radical polymerization. The studied monomer was methyl methacrylate (MMA). NaI and KI were dissolved in MMA through the addition of crown ethers and a polyether, i.e., diethylene glycol dimethyl ether (diglyme). The polymer molecular weight and its distribution (M-w/M-n = 1.2-1.4) were well controlled with high conversions (e.g., 80-90%) in reasonably short times (3-6 h) at mild temperatures (60-70 degrees C) in the MMA polymerizations. The effects of the ethers on the polymerization behavior were systematically studied in this work.
