Abstract

Different types of the tridentate Schiff base, [N-(2-methoxyphenyl) salicylideneamine] derivative of lanthanoid complexes along with Al(i-Bu)/sub 3/ are proved to be versatile tools for the polymerization of methylmethacrylate (MMA). The complexes, derived from indene and tridentate Schiff base ligands, express better efficiency (Mv = 195 X 10/sup 3/ - 355 X 10/sup 3/) than the complexes, prepared from cyclooctatetraene (COT) and tridentate Schiff base ligands (Mv=105 X 10/sup 3/ - 175 X 10/sup 3/). The effect of catalyst, temperature, catalyst/MMA molar ratio and catalyst/Al(i-Bu)/sub 3/ molar ratio on the polymerization of MMA at 70 deg. C are studied. It is observed that ligand size and radius of the metal are important factors in determining the catalytic efficiency of the complexes
