Abstract

The past decade has witnessed a remarkable growth in the polymerization reactions that are catalyzed by postmetallocene complexes. In this report, three early transition metal catalysts based on TiCl4 and aliphatic linear saturated dicarboxylic acids (Oxalic, Malonic and succinic acid) have been synthesized and characterized and their catalytic activity in emulsion polymerization have been studied. Upon treatment with NaBPh4, the complexes have been found to remain robust and highly active for the polymerization of Methylmethacrylate even at very low co-catalyst /catalyst ratios. Moreover, the polymers synthesized have been found to be isotactic rich.
