Transparent thin films of silica‐containing organic copolymers have been obtained by combining organic photopolymerisation and the sol‐gel method. The samples have been characterized via IR spectroscopy, N2‐adsorption (77 K), thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). The viscoelastic nature of the materials have been investigated via the DMTA technique by applying stress to the samples and monitoring their responses. Textural properties such as: specific surface areas (SBET), pore volume (Vp), average pore sizes (Rp) and micropore volumes (VDR) have been obtained. The complete adsorption‐desorption isotherms and pore size distributions have been analyzed following the Dollimore‐Heal method.
