Effect of solvent polarity on the coordination polymerization of methyl methacrylate

Polymerization of MMA was carried out in four chlorine solvents (chlorobenzene, dichloro methane, chloroform, carbon tetra chloride) and toluene under equal reaction conditions by α-diimine coordination catalyst. The effect of polarity of the solution on the polymerization was investigated by changing the solvent. On the other hand tacticity of the synthesized polymers was determined by HNMR technique. All species have syndiotactic-rich structure
