A di-hydroxy-functionalized linear non-crosslinked polyolefin is disclosed having no pendant chain-branched groups which is prepared by reacting 1,4-diacetoxy-2-butene with 1,5-cyclooctadiene in the presence of a catalyst comprising a ruthenium metal carbene complex, characterized in that the functionality number of said polyolefin as determined by NMR is 2.0 and the viscosity of said polyolefin ranges from about 800 to 16000 mPa.cndot.s @25°C at a number average molecular weight ranging from 2,600 to 6,500 g/mole. A prepolymer comprising the reaction of a polyisocyanate with the polyolefin is also disclosed.
