摘要：
This application relates to cyclic siloxane compounds comprising the structural formula where a≧2 and b≧2, R is an alkyl group containing 1 to 4 carbon atoms, R1 is independently hydrogen or methyl, compositions comprising any of the above cyclic siloxanes and an additional silicone, emulsion compositions comprising any of the above cyclic siloxanes or the above composition, and a process for preparing the above cyclic siloxane compounds comprising reacting a chloro end-blocked polydimethylsiloxane with a diol functional compound containing at least 3 carbon atoms.
