Patent number: 7198878Abstract: The invention is a photoswitchable benzocyclobutene-based polymer that while remaining aqueous developable, avoids the problem of significant moisture uptake. The oligomer or polymer comprises a polymeric backbone, benzocyclobutene reactive groups, and photoswitchable pendant groups. The pendant groups are bonded to the polymeric backbone and are characterized by the presence of a moiety that converts to carboxylic acid upon exposure to activating wavelengths of radiation a carboxylic acid. When the oligomer or polymer is subsequently heated to cause cure of the oligomer or polymer, carbon dioxide is emitted and the group forms a substantially non-polar moiety. The invention is also a method of making such a polymer and a method of forming a patterned film using such a polymer.Type: GrantFiled: June 7, 2005Date of Patent: April 3, 2007Assignee: The Dow Chemical CompanyInventors: Ying Hung So, Scott J.

Patent number: 7145453Abstract: A method for detecting a latent environmental effect (such as a corrosive environment under insulation) or a latent structural change (such as a crack in a concealed structural member) at a known remote concealed location. The method of the instant invention includes three steps. The first step is to use a harmonic electromagnetic transponder at the known remote concealed location of the latent environmental effect or the latent structural change, the harmonic electromagnetic transponder having a reactive portion which reacts to the latent environmental effect or latent structural change to modify the harmonic emission of the transponder. The second step is to remotely interrogate the transponder by directing electromagnetic radiation at the transponder. The third step is to use the harmonic emission of the transponder to remotely determine the latent environmental effect or the latent structural change.Type: GrantFiled: September 2, 2004Date of Patent: December 5, 2006Assignees: The Dow Chemical Company, Michigan State UniversityInventors: Theodore E.

Patent number: 7135282Abstract: The present invention relates to the expression of peptides on viral particles, and more particularly to the expression of peptides on the interior or the viral capsid. Methods are described for modifying viruses so that exogenous epitopes are expressed on the interior of the viral capsid. Viruses that can be modified include (+) stranded RNA viruses, especially plant (+) stranded RNA viruses such as the cowpea mosaic virus. Internal expression is especially useful for the expression of hydrophobic epitopes. The modified viral particles also find use as vaccines and as such are capable of eliciting an immune response.Type: GrantFiled: October 13, 2000Date of Patent: November 14, 2006Assignee: The Dow Chemical CompanyInventors: Koen Hellendoorn, Tim Jones

Patent number: 6995234Abstract: In the present invention, an inorganic reactant is, or reactants are, localized with respect to a dendritic polymer by physical constraint within or by a non-covalent conjugation to the dendritic polymer. The localized inorganic reactant or reactants is/are subsequently transformed to form a reaction product which is immobilized with respect to the dendritic polymer. This immobilization occurs on a nanoscopic scale as a consequence of the combined effects of structural, chemical and physical changes without having covalent bonds between the product(s) and the dendritic container and results in new compositions of matter called dendritic nanocomposites. The resulting nanocomposite material can be used to produce revolutionary products such as water soluble elemental metals, with specific applications including magnetic resonance imaging, catalytic, magnetic, optical, photolytic and electroactive applications.Type: GrantFiled: October 9, 2003Date of Patent: February 7, 2006Assignee: The Dow Chemical CompanyInventors: Donald A.

Patent number: 6972078Abstract: A catalytic powder comprising a plurality of support metal particles with a porous coating (12) surrounding the metal particles (11), the porous coating comprising either an electrocatalytic metal or an electrocatalytic metal continuous phase in admixture with a particulate material (14). An electrode made with the catalytic powder and a method to make the electrode is also disclosed. The present invention is advantageous because the porous coating mixture is first applied to a powder rather than being applied directly to a metal substrate, thereby creating a large internal surface area on the electrode and accordingly, lower overpotential requirements.Type: GrantFiled: October 13, 2000Date of Patent: December 6, 2005Assignee: The Dow Chemical CompanyInventors: Yu-Min Tsou, Edmond L.
