Patent number: 6642322Abstract: A method of making telechelic oligomers comprises reacting a substrate compound selected from the group consisting of relatively high molecular weight polymers with a chain transfer agent in the presence of an alkali metal catalyst. The telechelic oligomers thus produced may then be reacted with monomers according to known polymerization techniques in order to produce block copolymers.Type: GrantFiled: September 27, 2001Date of Patent: November 4, 2003Assignee: The University of North Carolina at Chapel HillInventors: Michel R. Gagné, Michael R. Korn

Compatibilizing agent, radical polymerizable resin composition, molding material, and molded article
Publication number: 20030166775Abstract: An object of the present invention is to provide a practical compatibilizing agent which makes it possible to convert the resin mixture into a homogeneous resin mixture free from separation and to eliminate defects caused by separation on molding by prevention of the separation between the radical polymerizable unsaturated resin and low profile additive, which could have not been attained by the prior art.Type: ApplicationFiled: January 10, 2003Publication date: September 4, 2003Applicant: DAINIPPON INK AND CHEMICALS, INC.Inventors: Akira Takano, Takashi Yasumura -
Patent number: 6605236Abstract: A composition comprised of a composite comprised of an aromatic or heteroaromatic polymer comprised of monomer or monomers selected from the group consisting of pyrrole, indole, thiophene, thianaphthene, indene, azulene and ring pendant substitutent derivatives thereof as a discrete phase; and a block copolymer as a continuous phase selected from the group consisting of ionophoric and ionomeric copolymers, wherein the block copolymer has at least one apolar segment and at least one ion binding segment, wherein the ionomeric or ionophoric block copolymer is present in an amount from about 99 to about 50 percent by weight based on the combined weight of the block copolymer and the aromatic or heteroaromatic polymer, wherein the block copolymer provides micellar or vesicular domains for organization and polymerization of the monomer or monomers.Type: GrantFiled: January 3, 1994Date of Patent: August 12, 2003Assignee: Xerox CorporationInventors: Thomas W. Smith, David J. Luca

Patent number: 6579939Abstract: A golf ball is formed with a resin composition which contains 5 to 95 weight % of a polyester block copolymer (A) and 95 to 5 weight % of an ionomer resin (B); and a (polyester-aromatic vinyl based copolymer) block copolymer (C), which is mixed with both the polyester block copolymer (A) and the ionomer resin (B) in an amount of 1 to 40 parts by weight on the basis of 100 parts by weight of the total of the polyester block copolymer (A) and the ionomer resin (B). The polyester block copolymer (A) mainly contains a high-melting point crystalline polymer segment (a1) composed of a crystalline aromatic polyester unit, and a low-melting point polymer segment (a2) composed of an aliphatic polyether unit and/or an aliphatic polyester unit. The ionomer resin (B) is produced by neutralizing a copolymer mainly containing an &agr;-olefine (b1) and an &agr;,&bgr;-unsaturated carboxylic acid (b2) having 3 to 8 carbon atoms with at least one metal ion (b3) selected from univalent, divalent, and trivalent metal ions.Type: GrantFiled: February 5, 2001Date of Patent: June 17, 2003Assignee: Bridgestone Sports Co., Ltd.Inventors: Yasushi Ichikawa, Rinya Takesue, Eiji Takehana, Yoko Furuta

Patent number: 6570714Abstract: The invention is directed to a method for making composite articles, including optical lenses, which includes the steps of obtaining a substrate; placing a semi-solid-like polymerizable composition in contact with at least one of the front or back surface of the substrate; compressing or heating the resulting semi-solid/substrate sandwich between two mold halves, where the mold contacting the semi-solid polymerizable material has a desired surface geometry; and exposing the semi-solid/substrate sandwich to a source of polymerizing energy. The resulting composite article has the desirable characteristics of the substrate but is also easily fabricated as a result of the semi-solid molding process. Also included within the present invention is a composite article comprising a substrate portion and at least one layer of a cured resin bonded to the substrate portion, the cured resin comprising an interpenetrating crosslinked polymer network of reactive plasticizer within a dead polymer.Type: GrantFiled: December 5, 2001Date of Patent: May 27, 2003Assignee: ZMS, LLCInventors: David S. Soane, Michael R. Houston, Toshiaki Hino
