Studies on the Detailed Structure of Poly(dimethylsilylene)

The detailed structure of poly­(dimethylsilylene) was analyzed by 29Si and 13C CP/MAS NMR spectra and theoretical calculations. The end groups were assigned to methoxy and hydroxy groups. This assignment was also supported by the NMR measurement of model compounds. Branched structures are not present. A trace amount of siloxane bonds is contained. The degree of polymerization was estimated to be ca. 580–750 by the 29Si CP/MAS NMR spectra.
