| Abstract: | Polymerization of Vinyl Compounds in the Presence of Titanium(III)Chloride The polymerization of styrene, acrylonitrile and some methacrylates initiated by a titanium(III) chloride dichloroacetic acid redox system was studied. The monomer selectivity of the polymerization in the presence of titanium(III) chloride was found to be affected by a reductive termination reaction. Titanium(III) chloride acts as a retarder in the polymerization of styrene initiated by azobisisobutyronitrile (AIBN). The polymerization of polar monomers like acrylonitrile, methyl, ethyl and propyl methacrylate by AIBN is inhibited by titanium(III) chloride. |
