Inorganic-organic hybrids have been synthesized by reaction of Ti(OC{sub 2}H{sub 5}){sub 4} and Ta(OC{sub 2}H{sub 5}){sub 5} with silanol-terminated polydimethylsiloxane (PDMS). The chemical modification of the metal alkoxides with ethyl acetoacetate (EAcAc) was carried out in order to obtain a transparent and uniform hybrid. The hydrolysis behavior of Ti(OC{sub 2}H{sub 5}){sub 4} modified with EAcAc in the presence of PDMS and the formation of the Ti-O-Si bond in a Ti-O-PDMS hybrid were revealed by FT-IR experiments. Dynamic mechanical measurements showed that a Ta-O-PDMS hybrid was harder than a Ti-O-PDMS hybrid, indicating the effect of metal on the storage modulus of hybrids.
