<p>A cyclopolysiloxane having the general structure <CHEM> wherein Q is a monovalent siloxane moiety selected from the group consisting of the structure (R3SiO)2SiR-A- and the structure GR2SiOSiR2 -A'-, in which A is a divalent hydrocarbon group having 4 to 14 carbon atoms and A' is a divalent hydrocarbon group having 2 to 18 carbon atoms, each R' group and each G group is independently selected from the group consisting of an alkyl radical having 1 to 30 carbon atoms, a phenyl radical, an arylalkyl group and a halogenated alkyl radical having 3 to 6 carbon atoms, each R is independently selected from the group consisting of an alkyl radical having 1 to 30 carbon atoms, a phenyl radical, an arylalkyl group, a halogenated alkyl radical having 3 to 6 carbon atoms and hydrogen and x and y are each integers, with the proviso that (x + y) is an integer having a value of 4 to 6 inclusive and y is at least 1.</p> |
