Abstract:
Stable star-structured functional polyolefins and methods of making them, the functional polyolefins comprising a polyolefin bound at any position along its chain length to at least one nucleophile-containing silane of the following formula: wherein Y is a di- or trivalent linker group selected from heteroatoms, C1 to C10 alkylenes, and other groups disclosed herein; Nu is a nucleophilic atom or unsaturation group; R5 is selected from hydrogen, and C1 to C10 alkyls, and other groups as disclosed herein; X is a divalent group selected from linear and branched alkylenes and heteroatom-alkylenes, and other groups as disclosed herein; and PO is a polyolefin having a weight average molecular weight of at least 400 g/mole; with the proviso that at least one of R1, R2, and R3 is selected from the same or different functional polyolefin moieties. Star-structured functional polyolefins are useful as filler dispersive additives in tire formulations and processing aids.

Claim (Index 1):
A functional polyolefin comprising the reaction product of:\n (a) at least one polyolefin comprising at least one nucleophile-reactive group or unsaturation at one or both of the chain ends and/or inside the chain; and (b) at least one aminosilane compound of the following formula: wherein R1, R2, and R3 are independently selected from hydrogen, hydroxide, C1 to C10 alkoxys, C6 to C30 aryloxys, C7 to C30 arylalkyloxys, and C1 to C10 alkylamines, wherein any 2- or more groups can form an aliphatic or aromatic cyclic structure that includes the silicon atom; R5 and R6 are independently selected from hydrogen, C1 to C10 alkyls, C1 to C10 aminoalkyls, C6 to C20 aryls, C7 to C22 alkylaryls, C7 to C22 aminoaryls, and C7 to C22 arylalkyls; R7 and R8 are independently selected from C1 to C5 alkyls; each R9 is independently selected from hydrogen and C1 to C5 alkyls; each R10 is independently selected from hydrogen and C1 to C5 alkyls; each R11 is independently selected from hydrogen and C1 to C5 alkyls; each R12 is independently selected from hydrogen and C1 to C5 alkyls; m and n are each integers \u22650, wherein the sum of m and n ranges from 0 to 9; and wherein any one of R1, R2, or R3 may form a 5 to 10 membered alkylene or aminoalkylene ring with the nitrogen atom.
