The polymerization of epichlorhydrin (ECH) catalyzed by Maghnite-H+; (Mag-H+), a montmorillonite sheet silicate clay exchanged with protons, was investigated. The cationic ring-opening polymerization of epichlorhydrin was initiated by Mag-H+ at different temperatures (20, 30, 40, 50 and 60°C) in bulk and in a solvent. The effects of the amount of Mag-H+ and the temperature were studied. The polymerization rate and the average molecular weights increased with an increase in the temperature and the proportion of the catalyst. These results indicated the cationic nature of the polymerization and suggested that the polymerization was initiated by proton addition to the monomer from Mag-H+. Moreover, we used a simple method, in one step in bulk and in solution at room temperature (20°C), to prepare a telechelic bismacromonomer: α,ω-bisunsaturated polyepichlorhydrin. The telechelique polymer was characterized by means of 1H-NMR, FT-IR spectroscopy, UV and GPC.
