    摘要: The present description relates to an olefin block copolymer having excellences in elasticity, heat resistance, and processability. The olefin block copolymer includes a plurality of blocks or segments, each of which includes an ethylene or propylene repeating unit and an α-olefin repeating unit at different weight fractions. In the olefin block copolymer, a first derivative of the number Y of short-chain branches (SCBs) per 1,000 carbon atoms of each polymer chain contained in the block copolymer with respect to the molecular weight X of the polymer chains is a negative or positive number of −1.5×10−4 or greater; and the first derivative is from −1.0×10−4 to 1.0×10−4 in the region corresponding to the median of the molecular weight X or above.

    摘要: The present description relates to an olefin block copolymer preferably useful to form nonslip pads due to excellences in elasticity and heat resistance, and a sheet-shaped molded body comprising the olefin block copolymer The olefin block copolymer includes a plurality of blocks or segments, each of which includes an ethylene or propylene repeating unit and an α-olefin repeating unit at different weight fractions. The olefin block copolymer satisfies a defined relationship when a load of 5 to 10 kg is applied to a sheet-shaped molded body of the block copolymer for 12 hours or longer at a temperature of 60° C. or higher, and then removed.
