DISILOXANE COMPOUNDS AND THEIR USES

A disiloxane having the following structure. Formula (I), Where R1, R3, R4 and R5 are each independently selected from monovalent hydrocarbon radicals having 1 to 4 carbon atoms, aryl, and a hydrocarbon group of 6 to 20 carbon atoms containing an aryl group; R2 is selected from a branched or linear hydrocarbon group of 7 to 15 carbons, a substituted branched or substituted linear hydrocarbon group of 7 to 15 carbons an optionally substituted aryl group, and an alkyl hydrocarbon chain of 4 to 9 carbons having one or more aryl substituents of 6 to 20 carbon atoms or a branched or linear hydrocarbon group of 1 to 6 carbons when R1 and R3 are independently an aryl group, or a hydrocarbon group of 6 to 20 carbon atoms containing an aryl group; Z is a linear or branched divalent hydrocarbon radical of from 2 to 10 (inclusive) carbon atoms and R8 is selected from OH, H, monovalent hydrocarbon radicals of from 1 to 6 carbon atoms and acetyl and each of the subscripts a, b and c are zero or positive provided that a + b + c ≥ 1.
