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
## Abstract Comparison between fumed and precipitated silicas in their interactions with an oligomer of poly(dimethylsiloxane) showed both materials to exhibit general identical behavior depending on the experimental temperature range. However, the results obtained suggest on the one hand that thes
