**Abstract**
 Organic-inorganic interpenetrating polymer network(IPN) materials were prepared by hydrolysis and condensation of tetraethoxysilane(TEOS) in PVAl solution. The structure and morphology of the IPNs were investigated by FTIR spectroscopy and TEM. The thermal properties were examined by TGA and DSC. FTIR spectroscopy showed the formation of Si-O-C and Si-O-Si bonds in the system. TEM demonstrated a homogeneous dispersion of silica in the PVAl matrix when the amount of TEOS added was appropriate. DSC and TGA revealed that, compared with pure PVAl films, the hybrid films exhibited a higher Tg and high thermal stability. 17 refs.
