Application
A Practical Living Radical Polymerization with Sodium Iodide as a Catalyst

I0954

Typical Procedure (a bulk polymerization):
A mixture of methyl methacrylate (801 g, 8 mol), 2-iodo-2-methylpropionitrile (15.6 g, 80 mmol), sodium iodide (6 g, 40 mmol), and 18-crown-6-ether (10.6 g, 40 mmol) is heated in a flask at 70 °C for 4 h under an argon atmosphere with stirring. An aliquot (0.1 mL) of the solution is taken out by a syringe, cooled to room temperature, diluted by THF or DMF to a known concentration, and analyzed by gel permeation chromatography (GPC), yielding the polymer with Mn = 8200 and Mw/Mn = 1.16 (monomer conversion = 83%).

Application
Alkyl Iodide Initiators for Organocatalyzed Living Radical Polymerization

General Scheme of Organocatalyzed Living Radical Polymerization1-5)

Goto et al. have reported that alkyl iodides are efficient initiators for organocatalyzed living radical polymerization which is a new family of living radical polymerization. Organic amines, organic salts and sodium iodide are used as catalysts. 1-5) Low polydispersity and metal free polymers can be obtained by using this method.

 

Ranges of Effective Alkyl Iodides in the Polymerizations of Methyl Methacrylate (MMA) and Butyl Acrylate (BA)1)

These alkyl iodides are effective initiators in methyl methacrylate (MMA) [M0087] and butyl acrylate (BA) [A0142] polymerizations using tributylmethylphosphonium iodide (BMPI) [M1455] or tetrabutylammonium iodide (BNI) [T0057] as a catalyst. Low-polydispersity polymers are obtainable.1)
