Abstract
The characterization of 1-methyl-1-vinyl-3,3,5,5-tetraphenylcyclotrisiloxane by NMR(1H,13C,29Si) and X-ray crystallography is reported. The central siloxane ring is planar with Si–O bond lengths and angles which are similar to those found in the structures of other cyclotrisiloxanes. There is significant thermal motion of the methyl and vinyl groups. Very low incorporation of the siloxane is observed in the radical catalyzed copolymerization of the siloxane with styrene.
