Abstract
The polymerization of 2‐chloro ethyl vinyl ether (CEVE) catalyzed by the Maghnite‐H (Mag‐H+) was investigated. Mag‐H+ is a Montmorillonite sheet silicate clay exanchanged with protons. It was found that the cationic polymerization of 2‐chloroethyl vinyl ether is initiated by Mag‐H+ at 20°C in bulk and in solution. The effect of the amount of Mag‐H+, the temperature and the solvent was studied. The polymerization rate increased with increase of the temperature and the proportion of catalyst, and it was higher in dichloromethane than that in toluene. It may be suggested that the polymerization is initiated by proton addition to monomer from Mag‐H+. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
