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 <sup>29</sup>Si CP/MAS NMR spectra.
