Titanium tetrachloride and titanium tetraisopropoxide were purchased from Wako Pure Chemical Industries, Ltd. Trimethyl aluminum was purchased from Toyo Stauffer Chemical. 2,2 -Thiobis(4-methyl-6-t-butylphenol) (TBP) and 2,2 -methylenebis(4-methyl-6-t-butylphenol) (MBP) were suplied by Ciba-Geigy AG. These materials were used without purification.
