    摘要： Polyolefin diblock copolymers are prepared via a chain transfer reaction with a borane dimer compound during a transition metal-catalyzed olefin polymerization in a process that resembles a transformation from transition metal coordination polymerization to free radical polymerization via a borane end group. The polyolefin diblock copolymers may be represented by the following formula: (Transition Metal Prepared Polyolefin)-b-(Free Radical Prepared Polymer), wherein the polyolefin segment is a homo-, co- and ter-polymer prepared by transition metal (especially metallocene catalyst) coordination polymerization of at least one olefin, and the free radical prepared polymer segment is prepared by free radical polymerization of at least one vinyl monomer, such as styrene, maleic anhydride, acrylates, methacrylates and their mixtures. The resulting diblock copolymers are useful as the interfacial materials to improve the interaction between polyolefins and other materials.
