Özet

Zirconium, titanium and aluminum phthalate (PH, C8H4O4) and pyridine-2-carboxylate (Pyca, C6H4NO2) compounds were prepared by reaction of Zr, Ti and Al-alkoxides with phthalic acid (PHA) and pyridine-2-carboxylic acid (PycaH) in alcohol. All new complexes were characterized by a combination of elemental analysis, NMR and FTIR spectroscopy and used in polymerization of 3-glycidyloxypropyltrimethoxysilane (GPTS) in order to see their catalytic activity over epoxides. Especially, Al, Ti and Zr-phthalate catalysts were more effective in ring opening of GPTS when compared to Al, Ti and Zr-pyridine-2-carboxylate catalysts. Poly-GPTS were characterized by H-1, C-13 NMR and gel permeation chromatography (GPC). (C) 2012 Elsevier B.V. All rights reserved.
