The high dielectric polymers are combined with fillers, preferably ceramic fillers, to form two phase composites having high dielectric constants. Composites having about 30 to about 90% volume ceramic loading and a high dielectric base polymer, preferably epoxy, have been discovered to have a dielectric constants greater than about 60. Composites having dielectric constants greater than about 74 to about 150 are also disclosed. Also disclosed are embedded capacitors with capacitance densities of at least 25 nF/cm2, preferably at least 35 nF/cm2, most preferably 50 nF/cm2. Methods to increase the dielectric constant of the two phase composites having high dielectric constants are also provided.Type: GrantFiled: May 18, 2001Date of Patent: April 8, 2003Assignee: Georgia Tech Research Corp.Inventors: Ching-Ping Wong, Yang Rao

Patent number: 6518344Abstract: The present invention provides a new and improved flame retarded polyolefin composition that displays good retained physical properties upon aging. The composition also exhibits excellent moldability and it may be easily colored. In a preferred embodiment the composition includes a polyolefin, a halogen-containing flame retardant additive, from at least about 1.00% by weight to about 2.5% by weight of a stabilizer package, and from about 0% to about 1.0% by weight of an acid/halogen scavenger. The stabilizer package includes by weight from about 20% to about 80% of a hindered phenolic antioxidant, from about 20% to about 80% of a phosphite containing antioxidant, and from about 0% to about 40% of a thio-ester antioxidant. In addition to displaying excellent color and physical property development and retention characteristics, the composition of the present invention displays an improved UL94 vertical burn rating.Type: GrantFiled: August 18, 2000Date of Patent: February 11, 2003Assignee: Ferro CorporationInventors: Deenadayalu Chundury, Ann Mendel, Howard E. Munro, Roy C. Sanford

Patent number: 6518339Abstract: An additive that is used in conjunction with certain dibenzylidene sorbitol-type (DBS) clarifiers and acid scavengers within polyolefin resins to reduce the release of aldehydes from polypropylene material is disclosed. Hydrazides have been shown to be effective at removing residual aldehyde from polyolefins, such as polypropylene. This function can be accomplished with a minimal impact on optical transparent properties imparted to the polypropylene by the clarifying agent. The net effect is an improvement in the organoleptic performance of resins containing clarifiers, and a reduction in the UV-absorbing extractables. Particularly, adipic dihydrazide, when co-compounded into polypropylene homopolymer with 4-methyl DBS, improves the organoleptic performance of the clarifier. Incorporation of dihydrazides into polypropylene pellets reduced air-released aldehyde by nearly 100%.Type: GrantFiled: September 18, 2000Date of Patent: February 11, 2003Assignee: Milliken & CompanyInventors: Shawn R. Sheppard, John G. Lever
