Patent number: 5043400Abstract: A method for producing articles of composite resin, wherein a liquid crystal polymer material in powder form is mixed with a second, melt-processable polymer material; the resulting mixture is kneaded at a temperature at which the second polymer material will melt but at which no deformation of the liquid crystal polymer will be caused so as to prepare a blend comprising the liquid crystal polymer powder uniformly dispersed in the matrix of the second polymer; and the blend is then subjected to a molding or shaping process at a temperature within the range at which the liquid crystal polymer is capable of forming liquid crystals.Type: GrantFiled: January 23, 1991Date of Patent: August 27, 1991Assignee: Tosoh CorporationInventors: Akeharu Tsuruta, Hisato Kawaguchi, Tomohiro Ishikawa, Yozo Kondo

Patent number: 5039742Abstract: Solvent-resistant resin blends, capable of being molded into parts which vary in properties relatively little over a wide range of molding conditions, are prepared from a polyphenylene ether, a linear polyester such as a poly(alkylene dicarboxylate), a mixture of a bisphenol A homopolycarbonate and block copolymer of a polyphenylene ether and a bisphenol A polycarbonate. Said blends preferably also contain at least one elastomeric polyphenylene ether-compatible impact modifier.Type: GrantFiled: October 30, 1989Date of Patent: August 13, 1991Assignee: General Electric CompanyInventors: Sterling B. Brown, John R. Campbell, Timothy J. Shea

Patent number: 5017656Abstract: The odor of blends of polyphenylene ether resin, alone, or in combination with a polystyrene resin or a high impact polystyrene is improved by including a carboxylic acid, an acid anhydride or mixture thereof in the compositions.Type: GrantFiled: June 13, 1988Date of Patent: May 21, 1991Assignee: General Electric CompanyInventor: Richard C. Bopp
-
Patent number: 4983677Abstract: An extrudable composition comprising hydrocarbon polymer, organophosphite or organophosphate compound and fluorocarbon polymer. The organophosphite or organophosphate and the fluorocarbon polymer are present in the composition in such relative proportions and concentrations as to reduce the occurrence of melt defects during the extrusion of said thermoplastic hydrocarbon polymer.Type: GrantFiled: July 18, 1989Date of Patent: January 8, 1991Assignee: Minnesota Mining and Manufacturing CompanyInventors: Bryce V. Johnson, Joyce M. Kunde
