20080051482 - Foams containing silicon: Both flexible and rigid foams may be prepared by reacting di- or polyisocyanates with organopolysiloxanes which are prepared by reaction of silanol-terminated organopolysiloxanes with organosilicon compounds containing alkyleneoxy or alkylenamino groups bonded on both ends to silicon, thus resulting in organopolysiloxanes having 95% or more of aminoalkyl or hydroxyalkyl terminal... Agent: Brooks Kushman P.C.

20080045616 - Method for fabricating a composite solid polymer electrolyte membrane: The present invention discloses a method for fabricating a composite solid polymer electrolyte membrane, wherein a flushed and dried membrane is sulfonated with sulfuric acid; the sulfonated membrane is flushed and dried once more; a first polymer solution is mixed with a second polymer solution, which has been hydrolyzed and... Agent: Sinorica, LLC

20080045615 - Polymer electrolyte; and an electrochemical device equipped with such a polymer electrolyte: Disclosed is a polymer electrolyte for use in an electrochemical device. Said polymer electrolyte comprises at least one polymer having ion-exchangeable functional groups. The polymer also comprises ionic liquid functional groups. The ion-exchangeable functional groups comprise a polymer-bound anionic group, such as a sulfonate, a carboxylate, and a phosphonate or... Agent: Philips Intellectual Property & Standards

20080045617 - Method for recycling a cross-linked polymer: A cross-linked polymer is recycled by decomposing a C—C bond by an oxidative decomposition reaction using a nitrogen oxide in a supercritical carbon dioxide. A reaction temperature, a pressure and a reaction time are controlled such that a nitrogen oxide is sorbed at a branch point of a C—C bond... Agent: Mcginn Intellectual Property Law Group, PLLC

20080039540 - Process for recycling polyesters: The present invention is directed towards a process for the recycling of polyesters comprising the steps of blending a starting polymer that is to be recycoled with an alkylene diol to form a blend, melting the blend and holding the melt blend under conditions of a first residence time, first... Agent: E I Du Pont De Nemours And Company Legal Patent Records Center

20080039541 - Latex with reduced odor: The present invention refers to a polymer latex made by free-radical polymerization comprising polymer particles containing structural units derived from at least one conjugated diene monomer and at least one aromatic vinyl monomer, whereby no vinyl pyridine is used in the polymerization and the polymer latex is polymerized in the... Agent: Knobbe Martens Olson & Bear LLP

20080033069 - Processes for producing nano-space controlled polymer ion-exchange membranes: A polymer film substrate is irradiated with ions to make a large number of nano-sized through-holes and the substrate may be further irradiated with ionizing radiation so that a functional monomer may be grafted or co-grafted onto a surface of the film and within the holes; in addition, sulfonic acid...
