Patent ID: 8198207

Claim:
A catalyst complex having a formula: where subscript x is one or more, subscript y is one or more, R 1 , R 2 , and R 3 are each independently selected from the group consisting of hydrogen, a cycloalkyl group, a linear or branched alkyl group having 1-12 carbon atoms, an alkylaryl group, an organosilane group, an organosiloxane group, an alkylene group capable of functioning as a covalent bridge to another boron atom, a divalent organosiloxane group capable of functioning as a covalent bridge to another boron atom, and substituted analogs thereof; where at least one of the R 1 , R 2 , or R 3 groups optionally contains one or more silicon atoms, and the silicon-containing group is covalently attached to boron, and where R 4 comprises units of formula (IV): where subscript j ranges from 1 to 700, subscript k ranges from 1 to 300, each R 10 is independently a divalent organic group, a divalent silicone group, or a divalent silicone-organic block copolymer, each R 12 is independently a divalent organic group, each R 18 is independently selected from the group consisting of an alkyl group, a halogenated alkyl group, a chain comprising siloxane, and an aryl group.
