摘要：

A set of porous silica has been grafted with trialkoxysilane coupling agents carrying either a gamma-propyl methacryloyl group, a gamma-propyl thiol or a gamma-propyl amine group. The grafts have been characterized by diffuse reflectance Fourier transform infrared spectroscopy and Si-29 and C-13 cross-polarization magic-angle-spinning nuclear magnetic resonance; the grafting yields were estimated from elemental analysis. The grafted amine was further reacted with azobiscyanovaleric acid. The grafted materials are to be used as co-monomer, transfer agent or initiator for a further grafting of a functional polymer via a radical polymerization.
