Poly(dimethylsiloxane) networks were prepared by tetrafunctionally endlinking hydroxyl-terminated chains with tetraethoxysilane (TEOS). Molecular composites were then prepared by in situ sol-gel reactions on additional TEOS swelled into the networks, resulting in the formation of reinforcing silica
