Patent number: 7169872Abstract: This invention describes novel chemical compounds whose structures are hybrids between sulfur-containing and non-sulfur-containing silanes wherein the two types of silanes are linked by siloxane bonds. The invention includes methods of preparation for the hybrid silanes as well as their use in filled rubbers as coupling agents. The hybrid silanes described are unique in that a certain amount of water in their preparation leads to superior performance in their intended application, and that they can thus be produced more efficiently and safely than coupling agents currently used in the art, from readily available hydrated raw materials.Type: GrantFiled: April 30, 2002Date of Patent: January 30, 2007Assignee: General Electric Co.Inventor: Richard W. Cruse

Patent number: 7122079Abstract: The present invention includes a composition for a silicon-containing material used as an etch mask for underlying layers. More specifically, the silicon-containing material may be used as an etch mask for a patterned imprinted layer comprising protrusions and recessions. To that end, in one embodiment of the present invention, the composition includes a hydroxyl-functional silicone component, a cross-linking component, a catalyst component, and a solvent. This composition allows the silicon-containing material to selectively etch the protrusions and the segments of the patterned imprinting layer in superimposition therewith, while minimizing the etching of the segments in superposition with the recessions, and therefore allowing an in-situ hardened mask to be created by the silicon-containing material, with the hardened mask and the patterned imprinting layer forming a substantially planarized profile.Type: GrantFiled: February 27, 2004Date of Patent: October 17, 2006Assignee: Molecular Imprints, Inc.Inventors: Frank Y. Xu, Michael N. Miller, Michael P. C. Watts

Patent number: 6972312Abstract: Three processes for the manufacture of polyhedral oligomeric silsesquioxanes (POSS) which utilize the action of bases that are capable of either attacking silicon or any compound that can react with a protic solvent (e.g. ROH, H2O etc.) and generate hydroxide [OH]?, alkoxide [RO]??, etc. The first process utilizes such bases to effectively redistribute the silicon-oxygen frameworks in polymeric silsesquioxanes [RSiO1.5]28 where ?=1-1,000,000 or higher into POSS nanostructures of formulas [(RSiO1.5)n?#, homoleptic, [(RXSiO1.5)n]?#, functionalized homoleptic, [(RSiO1.5)m(R?SiO1.5)n]?#, heteroleptic, and {(RSiO1.5)m(RXSiO1.0)n}?#, functionalized heteroleptic nanostructures. The second process utilizes base to aid in the formation of POSS nanostructures of formulas [(RSiO1.5)n]?# homoleptic and [(RSiO1.5)m(R?SiO1.5)n]?# heteroleptic and [(RSiO1.5)m(RXSiO1.Type: GrantFiled: August 4, 2000Date of Patent: December 6, 2005Assignee: Hybrid Plastics LLCInventors: Joseph D.
