摘要： Semi-crystalline, thermoplastic polyolefin block copolymers comprising: (A) A first polyolefin A block comprising isotactic poly(1-butene) (iPB); (B) A polyolefin B block comprising an ethylene and/or alpha-olefin/1-butene copolymer or terpolymer; and (C) A second polyolefin A block comprising isotactic poly(1-butene) (iPB); the A and B blocks bonded to one another to form a block copolymer in which the first and second polyolefin A blocks are joined to and separated by the polyolefin B block. In one embodiment the polyolefin block copolymer is a BAB block copolymer.

摘要： Catalyst compositions and polymerization systems include at least one thiourea complex according to Formula (I): MQaX4-a (I) in which M is Ti, Zr, or Hf; a is 1 or 2; each group Q of the thiourea complex is a bidentate thiourea ligand bound to the metal center and having Formula (Ia), Formula (Ib), or Formula (Ic): (Formulas should be inserted here). In Formulas (Ia), (Ib), and (Ic), each group R1, R2, and R3 is independently chosen from alkyl groups or aryl groups; each group Z1 or Z2 is independently chosen from alkylene groups. If a=2, groups R1 of the two groups Q are optionally linked, or groups R3 of the two groups Q are optionally linked. Each X is covalently bonded or coordinated to the metal center and is independently chosen from alkyl groups or halides. The polymerization systems may be configured to copolymerize ethylene and α-olefins.
