Abstract
The reaction of Ti(OPri)4(TIP) with alkanolamines and an association of the resultant Ti species were examined via NMR, IR, and cryoscopy measurements. Regardless of the kinds of the alkanolamines, alcohol exchange reactions occurred between the alcoholic moieties in alkanolamines and the isopropoxy groups in TIP and the N atom in the alkanolamines might be datively bonded to Ti. In the systems with the molar ratio of amine / TIP = 1, an association degree of the formed Ti species increased with increasing the concentration of TIP according to thermodynamical equilibriums of associations between various oligomers.
