Abstract:

A polyolefin-polybutadiene block-copolymer and a tire tread composition comprising the polyolefin-polybutadiene block-copolymer, the composition comprising, by weight of the composition, within the range from 15 to 60 wt % of a styrenic copolymer, processing oil, filler, a curative agent, and from 4 to 20 wt % of a polyolefin-polybutadiene block-copolymer, wherein the polyolefin-polybutadiene block-copolymer is a block copolymer having the general formula PO-XL-fPB; where “PO” is a polyolefin block having a weight average molecular weight within the range from 1000 to 150,000 g/mole, the “fPB” is a functionalized polar polybutadiene block having a weight average molecular weight within the range from 500 to 30,000 g/mole, and “XL” is a cross-linking moiety that covalently links the PO and fPB blocks; and wherein the maximum Energy Loss (Tangent Delta) of the immiscible polyolefin domain is a temperature within the range from −30 C. to 10 C.
