摘要：

Vinyl triethoxysilane (VTES) and (meth)acrylate monomers were mixed to create covalently bonded inorganic/organic copolymers, with and without tetraethyl orthosilicate (TEOS). Vinyl groups underwent free radical polymerization along with copolymerization with (meth)acryl groups of the monomer. For the two-monomer system, (meth)acrylate monomer and VTES, polymerization resulted in mechanically strong copolymers with flexure strengths greater than 40 MPa. Three-component materials obtained by polymerization of (meth)acrylate monomer, VTES and TEOS were homogeneous, highly transparent, with flexure strengths similar to those for silica xerogels, about 20 Mpa.
