The preparation of organic–inorganic polymer hybrids consisting of carbon–carbon and siloxane chains was investigated by radical polymerization of 3‐methacryloxypropyltrimethoxysilane (MAS) followed by acid‐catalyzed hydrolytic polycondensation. The condensation of poly(3‐methacryloxypropyltrimethoxysilane) (S‐PMA) of various molecular weights M n =830–12000 prepared by polyaddition provided transparent and flexible free‐standing hybrid gel films. The mechanical properties of these films were highly dependent on the carbon–carbon chain length: with an increase in the carbon–carbon chain length, the elasticity of gel films increased, while the tensile strength and Young's modulus decreased. Hydrolyzability of S‐PMA decreased with an increase in the carbon–carbon chain length, resulting in the formation of rubber‐like films with flexibility. © 1998 John Wiley & Sons, Ltd.
