Patent number: 7795347Abstract: A group of polymers comprising a plurality of polyolefin chains and polar polymer chains and having a multi-branched structure such as a block structure, a graft structure and a star-shaped structure is produced efficiently by polymerizing or reacting a combination of various polar monomers and their polymers i.e. polar polymer chains by using a functional group-containing polyolefin as a macroinitiator, a macromonomer or a reactive polymer. The resulting multi-branched polymer has a specific shape such as a block structure, a graft structure or a star-shaped structure, and has properties of both the polyolefin and polar polymer, thus exhibiting useful performance in various uses in films and compatibilizing agents as a novel polyolefin-based polymer.Type: GrantFiled: March 11, 2004Date of Patent: September 14, 2010Assignee: Mitsui Chemicals, Inc.Inventors: Hideyuki Kaneko, Tomoaki Matsugi, Shin-Ichi Kojoh, Shingo Matsuo, Nobuo Kawahara, Norio Kashiwa

Patent number: 7776971Abstract: The inventive subject matter relates to novel synthetic processes which use a multifunctional compound (the “TERMINI compound”) having a masked or protected functional group, wherein the TERMINI compound is capable of quantitatively and irreversibly interrupting a living polymerization or a chain organic reaction. After deprotection or demasking of the functional group of the TERMINI compound, the same living polymerization or organic reaction resumes with 100% efficiency, or a different living polymerization or organic reaction resumes with 100% chemoselectivity, respectively. Once incorporated into a growing molecule, the TERMINI compound generates a branching point upon resumption of the polymerization or reaction.Type: GrantFiled: May 6, 2004Date of Patent: August 17, 2010Assignee: The Trustees Of The University Of PennslyvaniaInventor: Virgil Percec
