ABSTRACT:
Branched monofunctional polysiloxanes are disclosed having the general formula:in-line-formulae description="In-line Formulae" end="lead"?X-(Da)-(DbTc),in-line-formulae description="In-line Formulae" end="tail"?wherein X-(Da) is a linear moiety and (DbTc) is a branched moiety; X a substituted or unsubstituted, monovalent or divalent hydrocarbon having a functional group;R5and R6are independently halogenated or unhalogenated monovalent hydrocarbon or substituted or unsubstituted divalent hydrocarbon;in-line-formulae description="In-line Formulae" end="lead"?T is (R7)dSiO(4-d)/2in-line-formulae description="In-line Formulae" end="tail"?R7is a substituted or unsubstituted monovalent hydrocarbon; wherein the branched polysiloxane is end-capped byR8is a substituted or unsubstituted monovalent hydrocarbon; a is 1 to 300, b is 25 to 5000, c is 1 to 100, d is 0 or 1; and Tcis randomly distributed in the branched polysiloxane. Additionally, processes for preparing such polysiloxanes, and coating compositions comprising the same is provided. A fuser member and substrate comprising a branched monofunctional polysiloxane of the above formula are also disclosed.
