Abstract : A new, inherently fibrous organosilicon polymer having pendent trimethylsilyl groups is reported. It has been made from the rare ladder or tube silicate litidionite using a Lentz-type extraction-substitution process. The constituent fibers of this polymer have very small diameters, often 40-60 A, and are flexible and inert. They are believed to have frameworks closely related to that of the parent silicate ion. A polymer which appears to be the same as this one has been made from the synthetic silicate, Na2CuSi4O10, a close structural analog of litidionite. In addition a related polymer carrying dimethylvinyl groups has been made from litidionite by a like Lentz-type procedure. Both silicates have been made by simple thermal procedures. (Author)
