Abstract: A multilayer cation exchange membrane for use in a chloralkali process comprising an carboxylate layer comprising a fluorinated ionomer containing carboxylate groups on one side of the membrane, an exterior sulfonate layer comprising a fluorinated ionomer containing sulfonate groups on the side of the membrane opposite the carboxylate layer, and an interior sulfonate layer comprising a fluorinated ionomer containing to sulfonate groups between the carboxylate layer and the exterior sulfonate layer, the exterior sulfonate layer having an ion exchange ratio greater than about 11.3, and the interior sulfonate layer having an ion exchange ratio less than about 11.

Abstract: The invention is directed to a photo-imageable composition precursor, the precursor composition comprising: (I) finely divided particles of inorganic material comprising: Functional phase particles selected from electrically conductive, resistive, and dielectric particles; inorganic binder having a glass transition temperature in the range of from 325 to 600° C.

Abstract: A polymeric film composition, which can readily be applied to a sheet-configured substrate and which resists creep at room temperature, even when the sheet/film combination is stored as a roll, is disclosed. The polymeric film composition has a viscosity of at least 3×106 Pa-s at a predetermined first lower temperature and at a shear stress of 10,000 Pa and a viscosity no greater than 1×104 Pa-s at a predetermined second higher temperature and at a shear stress of 50,000 Pa.
