Publication number: 20090205818Abstract: A downwell packer assembly includes a tubular member and a packer element mounted on the tubular member. The packer element comprises a composition that includes a polymer. The packer element includes micropores (typically created via a blowing agent). When the packer element is exposed to a swelling fluid, such as water or hydrocarbon, the micropores can help to control and, in some instances, increase the rate of swelling. Such swelling enables the packer element to form a seal against the walls of the wellbore.Type: ApplicationFiled: February 6, 2009Publication date: August 20, 2009Inventors: Jurgen Klunge, Bernd Jansen, Andreas Lutz

Patent number: 7541420Abstract: A method for preparing a molded article includes the steps of (a) obtaining a polycarbonate resin and (b) molding the polycarbonate resin. The polycarbonate resin is made by a transesterification reaction using an activated diaryl carbonate such that the polycarbonate is susceptible to the formation of internal ester linkages (IEL). The method occurs with the proviso that the polycarbonate resin, the molding conditions or both are selected to control the amount of IEL formed during the molding process to a level of less than 0.4 mol %.Type: GrantFiled: March 20, 2007Date of Patent: June 2, 2009Assignee: Sabic Innovative Plastics IP B.V.Inventors: Sjef Berndsen, Hans Peter Brack, Bernd Jansen, Jan Henk Kamps, Edward Kung, Daniel Lowery, Patrick Joseph McCloskey, Paul Michael Smigelski, Jr., Dennis Willemse

Patent number: 7498400Abstract: Polycarbonates incorporating terminal carbonate groups derived from ester-substituted activated carbonates in a transesterification process have unfavorable properties with respect to color, hydrolytic stability and thermal stability, particularly when the polycarbonate containing such end groups is molded. The number of activated carbonate end groups formed during the melt transesterification formation of polycarbonate can be reduced by reacting a dihydroxy compound with an activated diaryl carbonate in the presence of an esterification catalyst to produce a polycarbonate, in the presence of a monohydroxy chainstopper such as para-cumyl phenol in an amount that results in 35 to 65 mol % of the end groups being derived from the monohydroxy chainstopper. Suitably, the reactants are provided such that the molar ratio of activated diaryl carbonate to the total of dihydroxy compound plus ½ the chainstopping reagent that is less than 1.Type: GrantFiled: June 30, 2006Date of Patent: March 3, 2009Assignee: Sabic Innovative Plastics IP B.V.Inventors: Bernd Jansen, Jan Henk Kamps, Edward Kung, Patrick Joseph McCloskey, Paul Michael Smigelski, Jr.

Patent number: 7482423Abstract: Polycarbonates incorporating terminal carbonate groups derived from ester-substituted activated carbonates, for example terminal methyl salicyl carbonate (TMSC) derived from the use of BMSC as the activated carbonate in a transesterification process, have unfavorable properties with respect to color, hydrolytic stability and thermal stability, particularly when the polycarbonate containing such end groups is molded. The number of activated carbonate end groups formed during the melt transesterification formation of polycarbonate can be reduced, however, without sacrificing the benefits of using an activated diaryl carbonate, and without requiring a separate reaction or additional additives by reacting a dihydroxy compound with an activated diaryl carbonate in the presence of an esterification catalyst to produce a polycarbonate, wherein the molar ratio of activated diaryl carbonate to dihydroxy compound is less than 1 when expressed to at least three decimal places, for example 0.996 or less.Type: GrantFiled: June 30, 2006Date of Patent: January 27, 2009Assignee: Sabic Innovative Plastics IP B.V.Inventors: Bernd Jansen, Jan Henk Kamps, Edward Kung, Patrick Joseph McCloskey, Paul Michael Smigelski, Jr.
