Summary:abcabc 5 6 7d(4-d)/2 7 8 c Branched monofunctional polysiloxanes are disclosed having the general formula: X-(D)-(DT), wherein X-(D) is a linear moiety and (DT) is a branched moiety; X a substituted or unsubstituted, monovalent or divalent hydrocarbon having a functional group; Rand Rare independently halogenated or unhalogenated monovalent hydrocarbon or substituted or unsubstituted divalent hydrocarbon; T is (R)SiO Ris a substituted or unsubstituted monovalent hydrocarbon; wherein the branched polysiloxane is end-capped by Ris 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 Tis 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.
