Olefin block copolymers excellent in affinity with metal, polar resins or the like, impact resistance, mar resistance,nthermal resistance, rigidity, oil resistance, transparency, antifogging properties, electrical insulation properties, breakdown voltage,napplication properties, low-temperature flexibility, moldability, environmental degradation properties, fluidity and/or dispersionnproperties; and processes for producing the block copolymers. The block copolymers are represented by the general formula (I):nPO? 1 -¿ g 1 - B 1 (wherein PO 1 is a segment composed of repeating units derived from C 2-20 olelin; g 1 is an ester, ether, amide, imide,nurethane, urea, silyl ether, or carbonyl linkage; and B 1 is an unsaturated hydrocarbon or heteroatom-containing segment). |
