Patent number: 6664305Abstract: A process of manufacturing of a chromatography material comprising the steps of (i) reacting a polymerizable at least bifunctional monomer A with a ligand also having a functional group which binds covalently with one of the functional groups of said polymerizable bifunctional monomer A, (ii) to form a compound B comprising at least one polymerizable functional moiety (iii) polymerizing the compound B essentially alone or with the polymerizable monomers in presence of porogenes to obtain a block of porous polymerizate which is self-supporting or (iv) reacting the ligand and a spacer via a covalent bond which is cleavable to form a ligand-spacer conjugate and binding the ligand-spacer conjugate to the surface of a chromatographic support or reacting the ligand-spacer conjugate via a covalent bond to the at least bi-functional monomer A and polymerizing it essentially alone or with the polymerizable monomers in presence of porogenes to obtain a block of porous polymerizate which is self-supporting.Type: GrantFiled: October 28, 2002Date of Patent: December 16, 2003Assignee: BIA Separations d.o.o.Inventors: Alois Jungbauer, Rainer Hahn, Ales Podgornik, Milos Barut, Ales Strancar

Publication number: 20030220454Abstract: A halogenated butyl polymer having improved properties, the butyl polymer derived from a monomer mixture comprising a C4 to C8 monoolefin monomer, a C4 to C14 multiolefin monomer and a styrenic monomer with a catalyst system to produce the butyl polymer. The improved properties include faster cure, higher maximum torque, higher delta torque, relatively stable modulus over time, improved hot air aging properties and improved aged flexure properties. These improved properties are believed to result from direct interaction between the styrenic moieties in the polymer backbone with a crosslinking agent added to vulcanize the halogenated butyl rubber.Type: ApplicationFiled: March 17, 2003Publication date: November 27, 2003Inventor: Gabor Kaszas

Patent number: 6653410Abstract: Disclosed is a treating method of a resin composition comprising: kneading a resin composition comprising a thermoplastic resin, 0 to 0.7 part by weight, based on 1 part by weight of the thermoplastic resin, of a treating agent having a capacity of hydrogenating a halogen and a halide, at 280 to 450° C., in the presence of a metal compound which combines with a halogen atom to generate a metal halide compound having a boiling point or sublimation point not greater than 450° C. at atmospheric pressure, to thereby convert the halide into a metal halide; and separating and collecting, from the resin composition, each of a mixture of the thermoplastic resin and the treating agent having a capacity of hydrogenating a halogen, and the metal halide. This makes it possible to treat a waste without conducting gasification or liquefaction of a resin by combustion or thermal decomposition, thereby removing and collecting the halogen such as bromine and the metal oxide therefrom in a high yield in a short time.Type: GrantFiled: December 27, 2001Date of Patent: November 25, 2003Assignee: Asahi Kasei Kabushiki KaishaInventors: Takeshi Fujisawa, Yoshiyuki Arai, Hiroshi Mikami

Patent number: 6645562Abstract: A method of preparing a curable coating and a method of curing the curable coating are disclosed. The curable composition from which the curable coating is prepared may be applied to the surface of a substrate in neat form or in aqueous medium to produce the coating. Curing of the curable coating may be accomplished by chemical generation of free radicals, by electrochemical generation of free radicals, by electron beam, by photochemical generation of free radicals, or by other electromagnetic irradiation.Type: GrantFiled: June 27, 2002Date of Patent: November 11, 2003Inventors: Gary David Greenblatt, Ward Thomas Brown, Michael Damian Bowe, Richard Foster Merritt, Ronald Scott Beckley, Barry Clifford Lange, Robert Wilczynski, David William Whitman, Martha Harbaugh Wolfersberger

Publication number: 20030207983Abstract: A block copolymer comprising a polymer block [A] and a polymer block [B]. The polymer block [A] contains mainly a repeating unit having an alicyclic structure, and the polymer block [B] contains the repeating unit having an alicyclic structure and a repeating unit derived from a diene based monomer and/or a vinyl based monomer. In any block, the carbon-carbon unsaturated bonds are hydrogenated. The block copolymer is molded into optical disks, optical waveguides, films, sheets, containers, and optical lenses.Type: ApplicationFiled: January 31, 2003Publication date: November 6, 2003Inventors: Atsushi Sone, Tsutomu Nagamune, Masakazu Hashimoto, Toru Murata
