Process for functionalization of organo-metal compounds with silyl-based functionalization agents and silyl-functionalized compounds prepared thereby

A silyl-terminated polyolefin composition comprising a compound of the formula (IV):

• wherein
• Z comprises a linear, branched, or cyclic C1 to C20 hydrocarbyl group that is substituted or unsubstituted and is aliphatic or aromatic, wherein Z optionally includes at least one substituent selected from the group consisting of a substituted or unsubstituted metal atom, a substituted or unsubstituted heteroatom, a substituted or unsubstituted aryl group, and a substituted or unsubstituted cyclic alkyl group;
• subscript n is a number from 1 to 100,000;
• each RK is independently a hydrogen atom, a substituted or unsubstituted C1 to C25 hydrocarbyl group, or a leaving group selected from the group consisting of a halogen, a mesylate, a triflate, a tosylate, a fluorosulfonate, an N-bound five or six membered N-heterocyclic ring, an O-bound acetimide radical that is further substituted at a nitrogen atom, an N-bound acetimide radical that is optionally further substituted at an oxygen atom and/or at an nitrogen atom, an O-bound trifluoroacetimide radical that is further substituted at a nitrogen atom, an N-bound trifluoroacetimide radical that is optionally further substituted at an oxygen atom or a nitrogen atom, a dialkylazane, a silylalkylazane, or an alkyl-, allyl- or aryl sulfonate;
• and
• at least one RK is a hydrogen atom, and
• wherein the silyl-terminated polyolefin composition further comprises a metal compound comprising a divalent metal or a trivalent metal.
