Abstract Polymerizable organic silane molecules such as 3‐(trimethoxysilyl)propylmethacrylate (γ‐MPS) have been grafted onto the surface of ZrO 2 powders, via hydroxyl groups, to obtain hybrid ‘macromonomers’. A combination of x‐ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy and 29 Si nuclear magnetic resonance (NMR) spectroscopy have been employed to study the interaction between organic silane molecules and the surface of the ZrO 2 powders. The core‐level XPS regions, Zr 3d , O 1s , C 1s and Si 2p , have been studied to determine the nature of chemical bonding between the organic grafted monomer and inorganic phase and correlated with NMR results. Based upon the results obtained, it is proposed that grafting results in γ‐MPS bonded to the ZrO 2 powder surface via ZrOSi bonds accompanied by interlinkage of γ‐MPS molecules through SiOSi bonding. © 1997 John Wiley & Sons, Ltd.
