    摘要: The present description relates to an olefin block copolymer with excellences in elasticity, heat resistance, and processability. The olefin block copolymer comprises a plurality of blocks or segments, each comprising an ethylene or propylene repeating unit and an α-olefin repeating unit at different mole fractions. The olefin block copolymer comprises polymer chains containing 20 to 100 short-chain branches (SCBs) per 1,000 carbon atoms. A point where a first derivative of the number Y of the SCBs per 1,000 carbon atoms of each polymer chain with respect to the molecular weight X of the polymer chain is 0 exists between the minimum and maximum values of the molecular weight X.

    摘要: The present description relates to olefin block copolymers having excellent elasticity and processability in conjunction with enhanced heat resistance, and to a preparation method thereof. The olefin block copolymers comprise a plurality of blocks or segments that comprise ethylene or propylene repeating units and α-olefin repeating units at different mole fractions from one another, wherein the block copolymer shows peaks at the 2θ of 21.5±0.5° and 23.7±0.5° in a wide-angle x-ray diffraction (WAXD) pattern, and the peak ratio defined by (the peak area at 21.5±0.5°)/(the peak area at 23.7±0.5°) is no more than 3.0.
