Claim:
1. A polyolefin-polybutadiene block-copolymer that is the reaction product of a functionalized polar polybutadiene (fPB), a vinyl-terminated macromer (VTM), and optional cross-linker compound (XL): where the vinyl-terminated macromer comprises a polyolefin block (PO) having a weight average molecular weight within the range of from 1000 to 150,000 g/mole; the functionalized polar polybutadiene (fPB) having a weight average molecular weight within the range of from 500 to 30,000 g/mole; and the optional cross-linker compound (XL) comprises at least two cross-linking moieties wherein at least one moiety reacts with the vinyl group of the VTM (XL-PO) and at least one moiety reacts with the fPB (fPB-XL).
