Estimating the term…
A functionalized polyolefin and a tire tread composition comprising the functionalized polyolefin is described. The functionalized polyolefin comprises a vinyl/vinylidene-terminated polyolefin in which the vinyl/vinylidene terminus is functionalized with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality. The invention is also directed to the synthesis of vinyl/vinylidene-terminated polyolefins, functionalization at the vinyl/vinylidene terminus with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality.
A functionalized polyolefin comprising a aminoalkylsilyl-functionalized polyolefin (PO-aminoalkyl-Si), an alkylsilane-functionalized polyolefin, or an alkoxysilane-functionalized polyolefin, each having a polyolefin portion and a functional group attached thereto, wherein the polyolefin portion of the functionalized polyolefin has a weight-average molecular weight (Mw) within the range from 500 to 300,000 g/mole.
