Patent number: 7166687Abstract: A thermoplastic composition comprising a matrix of a polycarbonate polymer in which are embedded polysiloxane domains with an average domain size between 20 and 45 nanometers. Said compositions can be obtained by combining a first polycarbonate/poly(diorganosiloxane) copolymer; with a second polycarbonate/poly(diorganosiloxane) copolymer. A range of translucencies are obtainable by varying the relative amounts of the two copolymers without substantial loss in impact properties.Type: GrantFiled: February 20, 2004Date of Patent: January 23, 2007Assignee: General Electric CompanyInventors: Robert W. Venderbosch, Jan-Willem Goedmakers, Jeremy D. Hurst

Patent number: 7141640Abstract: An upflow reactor for the production of bisphenol A from acetone and phenol includes a vessel, a catalyst bed disposed within the vessel, and a reactant distribution/product collection system disposed within the vessel. The reactant distribution/product collection system includes a perforated distributor disposed at a lower end of the reactor. The reactant distribution/product collection system further includes a perforated collector disposed at an upper end of the reactor. A method for producing bisphenol A from acetone and phenol Includes Introducing the reacting mixture containing acetone and phenol to the distributor, directing it upward through the catalyst bed, and recovering the reacted acetone and phenol as bisphenol A together with other isomers and non reacted species. A method for avoiding catalyst bead carryover from the bed in an upflow reactor Includes receiving a product of the upflow reactor into the collector disposed at an upper end of the reactor through a screen with proper slit size.Type: GrantFiled: October 8, 2002Date of Patent: November 28, 2006Assignee: General Electric CompanyInventors: Hatem Belfadhel, Corinne Duchanoy, Jan-Willem Goedmakers, Eduard Hendricus Schlarmann, Monique I.
