Publication number: 20060160961Abstract: A method of preparing block copolyestercarbonates wherein al one dihydroxy-substituted aromatic hydrocarbon moiety and at least one aromatic diacid chloride are reacted under interfacial conditions to give a hydroxy-terminated polyester intermediate. The dihydroxy-substituted aromatic compound is used in about 10 mole to about 125 mole percent excess relative to the diacid chloride. Enhanced control of hydroxy-terminated polyester intermediate molecular weight is achieved by limiting the amount of water present to provide a final salt level of greater than 30 percent. The final salt level is a theoretical value but is readily calculable. The hydroxy-terminated polyester intermediate is then converted to a block copolyestercarbonate by reaction with a carbonate precursor such as phosgene.Type: ApplicationFiled: February 10, 2006Publication date: July 20, 2006Applicant: GENERAL ELECTRIC COMPANYInventors: Gregory O'Neil, Ali Acar, Paul Sybert, Pratima Rangarajan, Hongyi Zhou, Joseph Suriano

Publication number: 20050159543Abstract: A coating composition comprising components A, B and optionally C, wherein component A comprises at least one carboxy-terminated polyarylate. Component B is an organic species which can react with the terminal carboxy groups of component A, and component C is a catalyst or mixture of catalysts. The carboxy-terminated polyarylates are prepared by a solution polymerization method wherein a stoichiometric excess of a diacid chloride is reacted with a dihydroxy-substituted aromatic compound (e.g. resorcinol) in the presence of an organic base and a limited amount of water to produce an initially formed polyarylate comprising anhydride linkages. The initially formed polyarylate is then subjected to selective hydrolysis of the anhydride linkages to provide a low molecular weight carboxy-terminated polyarylate.Type: ApplicationFiled: April 6, 2004Publication date: July 21, 2005Inventors: Ali Acar, Rainer Koeniger, Glen Merfeld

Publication number: 20050159542Abstract: A composition comprising components A, B and optionally C, wherein component A comprises at least one carboxy-terminated polyarylate or an otherwise functionalized polyarylate. Component B is an organic species which can react with the reactive endgroups of component A, and component C is a catalyst or mixture of catalysts. The carboxy-terminated and functionalized polyarylates may be prepared by a solution polymerization method wherein a stoichiometric excess of a diacid chloride is reacted with a dihydroxy-substituted aromatic compound (e.g. resorcinol) in the presence of an organic base to provide an intermediate chlorocarbonyl group-substituted polyarylate which chlorocarbonyl groups may be elaborated to a variety of reactive endgroups including carboxy groups and epoxy groups.Type: ApplicationFiled: November 30, 2004Publication date: July 21, 2005Inventors: Ali Acar, Rainer Koeniger, Glen Merfeld

Patent number: 4319734Abstract: A ball valve having a cylinder slidable in a port. The cylinder has a lip which is pressed, by a spring, against a spherical surface surrounding a passage through the ball. A sleeve is slidable to a position over the cylinder, the sleeve having an annular groove adjacent the lip and a first seal therein. The sleeve has a portion contiguous to the cylinder at the end thereof opposite the lip, a second seal being provided between the housing and the sleeve portion. If C is the inside diameter of the lip, if B is the outside diameter of the length of the cylinder having the groove, if A is the outside diameter of the sleeve portion, if A>C, and if C>B, the valve will seal for flow in either direction or for zero flow all at, say, 3000 psi.Type: GrantFiled: March 9, 1981Date of Patent: March 16, 1982Assignee: International Telephone and Telegraph CorporationInventor: Ali Acar

Patent number: 4050477Abstract: A valve including a ball vibrated by a solenoid operated spring biased plunger wherein the ball is moved against one end of each of inlet and exhaust ports alternately in a somewhat oversized cavity to control, for example, the pressures on respective opposite sides of a displacement adjustable piston connected from the inlet port and cavity. The stroke of the piston may be made adjustable, if desired. The solenoid is energized with an A.C. source that has an adjustable frequency. An outstanding feature resides in the use of a needle valve at the other end of the inlet port. Tayloring can thereby be performed, whereas the same had not been otherwise possible in the prior art.Type: GrantFiled: October 31, 1975Date of Patent: September 27, 1977Assignee: International Telephone and Telegraph CorporationInventor: Ali Acar
