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.
