"[I]n the... early stage of polymer chemistry the question was raised on the ability of Si to generate chains... analogous to the s. ... (1912) isolated the compound SiH4, the chemical structure ...equivalent of (CH4). ...F. S. Kipping published his results on the preparation of the ... group (also called siloxo) Si-O-Si ...from the condensation of two groups and formation of water ...The ...reaction yielded ...organic mineral polymers known as s. ...Very soon after this ...it became evident that the silicone bridge -Si-O-Si- had something in common with the ...structure of (Almeningen et. al., 1963)."
