Patent number: 5486559Abstract: The invention relates to an optically non-linear active waveguiding material comprising an optically transparent polymer and a donor group and acceptor group-containing triphenylcarbinol as a dopant. Said dopants have a high hyperpolarizability and have a charge-transfer absorption band which is about the same as that of their corresponding compounds having only one donor-.pi.-acceptor unit. The triphenylcarbinols were found to display good solubility in polymers. Nitro-functionalized triphenylcarbinols are preferred because of their charge-transfer absorption band at a low wavelength (.lambda..sub.max at about 290 nm). Aldehyde-functionalized calix(4)arenes were also found to have this low wavelength charge-transfer absorption band (.lambda..sub.max at about 270 nm). Triphenyls comprising stilbene donor-.pi.-acceptor units are preferred because of their high hyperpolarizability.Type: GrantFiled: August 11, 1994Date of Patent: January 23, 1996Assignee: Akzo Nobel NVInventors: Johannes F. J. Engbersen, Erik Kelderman, David N. Reinhoudt, Willem Verboom

Patent number: 5300600Abstract: Disclosed are high concentration aqueous dispersions of normally solid organic peroxides using a dispersion agent comprising an alkylaryl polyether alcohol and an oxyalkylated phenolic resin. Optional components such as thickening agents, anionic emulsifiers and a partial ester of a carboxylic acid copolymer may also be included. Dispersions having concentrations of up to about 65% weight percent organic peroxide can be prepared. Dispersions having concentrations of up to about 40 weight percent organic peroxide are sprayable. Also disclosed are the curing of polyester resins and the suspension polymerization of vinyl monomers using these dispersions.Type: GrantFiled: May 7, 1992Date of Patent: April 5, 1994Assignee: Witco CorporationInventors: Lawrence A. Bock, Ronald L. Pastorino, Douglas Nordhaus

Patent number: 5102695Abstract: Clear, abrasion resistant, tintable coating compositions which are based on siloxane/silica hybrid coating resins and which also contain at least about 3 weight percent and up to about 30 weight percent of a tintability enhancing compound comprising at least one alkylated amine formadehyde compound. These coating compositions are especially useful for providing both abrasion resistance and high levels of tinting.Type: GrantFiled: November 14, 1990Date of Patent: April 7, 1992Assignee: Swedlow, Inc.Inventors: Allen M. Guest, Martin W. Preus, William Lewis

Patent number: 5006572Abstract: The invention relates to thermoplastic molding compositions comprising a polycarbonate resin which is rendered resistant to gamma radiation induced yellowing. It was surprisingly found that the incorporation in the resin of an effective amount of benzylic alcohol or its derivatized versions renders the composition resistant to yellowing. The composition of the invention is suitable for the preparation of molded articles having improved resistance to yellowing and to the formation of haze induced upon exposure to gamma radiation.Type: GrantFiled: September 5, 1989Date of Patent: April 9, 1991Assignee: Mobay CorporationInventors: Charles E. Lundy, Roger J. White, Sivaram Krishnan

Patent number: 4990550Abstract: Fiber-reinforced polymer compositions containing resin components including (a) 30-90 weight % of polyamide resins, and (b) 10-70 weight % of polyolefins+unsaturated carboxylic acid-modified polyolefins, based on the resin components; and (c) 5-50 parts by weight of glass fibers per 100 parts by weight of the total compositions, a molar ratio of end amino groups in the polyamide resins to carboxyl groups in the modified polyolefins being 10-1000. The compositions have a morphology in which polyolefin domains having an average size of 0.5-5 .mu.m are uniformly dispersed in polyamide matrix phases.Type: GrantFiled: March 20, 1989Date of Patent: February 5, 1991Assignees: Tonen Sekiyukagaku Kabushiki Kaisha, Nippondenso Co., Ltd.Inventors: Kunio Iwanami, Kissho Kitano, Kiyotada Narukawa, Kenichi Aoki, Yukihiko Yagi, Masato Sakuma, Takashi Mikami, Masami Esaki, Fumio Kato, Koji Egashira, Hiroyuki Wakabayashi
