Patent number: 6605682Abstract: The invention provides a resin molded article for optical products comprising a copolymer predominantly composed of methyl methacrylate and a styrenic monomer, wherein the number of foreign bodies contained in the resin molded article having a length of 210 mm, a width of 210 mm and a thickness of 3 mm as visually examined using a strain meter is about 150 or less, which is useful for a light transmitting plate employed in a liquid crystal display device because the possibility that the display screen looks whitely turbid due to the warp of the light transmitting plate, is reduced.Type: GrantFiled: March 28, 2001Date of Patent: August 12, 2003Assignee: Sumitomo Chemical Company, LimitedInventors: Ikuo Morisada, Kenji Manabe

Patent number: 6576161Abstract: The present invention relates to polyphosphate ester morpholides, compositions comprising mixtures thereof and thermoplastic resin compositions containing the polyphosphate ester morpholide composition as a flame retardant. The flame retardant compositions comprise mixtures of polyphosphate ester morpholides which are represented by the following general formula I: in which X is 1 or 2; R1 is a C6-C20 aryl group, an alkyl substituted C6-C20 aryl group or a derivative thereof; R2 is a C6-C30 arylene group, an alkyl substituted C6-C30 arylene group or a derivative thereof; n is the average number of morpholide repeating units, m is the average number of R1 repeating units, and n+m is 1 to 5. In accordance with the present invention, it is possible to provide a flame retardant thermoplastic resin compositions having improved flame retardancy even when small amounts of the flame retardant are used.Type: GrantFiled: November 28, 2001Date of Patent: June 10, 2003Assignee: Cheil Industries, Inc.Inventors: Jong-Cheol Lim, Kyung-Hoon Seo, Sam-Joo Yang

Publication number: 20030060543Abstract: The present invention provides additive packages for polyolefins The additive packages of the present invention comprise at least one non-phenolic antioxidant and a hindered amine light stabilizer. The additive packages may contain other additives as needed, and may optionally include an acid scavenger. Articles made from the resultant polymers, such as radiator surge tanks, exhibit enhanced stain and discoloration resistance upon exposure to high temperatures and harsh chemicals such as those experienced in “under the hood” spaces of modem automobiles.Type: ApplicationFiled: May 29, 2001Publication date: March 27, 2003Inventors: Steven David Seip, Sharon Edwards Thompson, Edwin B. Townsend

Patent number: 6409941Abstract: A product obtainable by transferring groups of formula (G-I) being present in a block oligomer having a polydispersity {overscore (M)}w/{overscore (M)}n of 1 to 1.7 and corresponding to formula (I) to groups of formula (Gu-II), wherein R1 is a hydrocarbyl radical or —O—R1 is oxyl; said transfer is carried out by reaction of the block oligomer with a hydroperoxide in a hydrocarbon solvent in the presence of a peroxide decomposing catalyst; n is a number from 2 to 14; R2 is for example C2-C12alkylene; A is for example —N(R4)(R5); R4 and R5 are for example C1-C18alkyl; R is preferably a group of formula (G-I) and B and B* have one of the meanings given for A; with the proviso that in the individual recurrent units of formula (I), each of the radicals B, R and R2 has the same or a different meaning. The products are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials, in particular synthetic polymers.Type: GrantFiled: November 18, 1999Date of Patent: June 25, 2002Assignee: Ciba Specialty Chemicals Corp.Inventors: James Peter Galbo, Nicola Lelli, Valerio Borzatta, Jean-Pierre Wolf, Michael Ackerman, Piero Piccinelli
