The adhesives of the present invention contain a polyimide base polymer present in the overall adhesive in an amount from 25 to 95 weight percent. The polyimide base polymer has a glass transition temperature (“Tg”) in a range of from about 150 to about 300° C. and typically has a coefficient of thermal expansion above 50 ppm/° C. The polyimide based adhesives of the invention also contain an aramid micro fiber filler in an amount from 5 to 75 weight percent, based upon the total weight of the polyimide based adhesive. The fiber filler can be used to lower CTE of the overall adhesive to match (or nearly match) the CTE of other materials like metal, silicon wafers, other polymers (including polyimide) and the like.Type: GrantFiled: March 31, 2006Date of Patent: September 7, 2010Assignee: E.

Patent number: 7763357Abstract: A one step synthetic route of polymeric compositions of a polyolefin and inorganic network consisting of components selected from Si, Zr, Ti, is disclosed. The synthetic route combines parallel reactions of free radical polymerization to form polymer, and hydrolysis of either Si, or Zr, or Ti or both of them precursors. The network consisting of Si, Zr, Ti, is chemically bonded to or within the polymer matrix. The inorganic or organic molecules can then be polymerized under conditions effective to cause the polymerized inorganic or organic molecules into macromolecular networks. The compositions of the polymeric composites can be easily controlled by adjusting the reactant ratio and reaction rate or conditions such as temperature and pressure, wherein the inorganic compositions disperse in nanoscale within polymeric composites when their concentrations fall below moderate levels.Type: GrantFiled: January 26, 2006Date of Patent: July 27, 2010Inventors: Paul A. Charpentier, Xinsheng Li
