  • Publication number: 20230311038
    Abstract: Electret webs include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is a substituted-benzoic acid or a substituted-benzoate salt. The benzoic acid and benzoate salts are substituted by a hydroxyl or amino group at the ortho position or 1 position of the benzene ring. The benzene ring may contain additional substituent groups. The substituted-benzoate salt may have a monovalent, divalent, or trivalent metal counteraction.

  • Publication number: 20070085212
    Abstract: A dielectric composite material containing a toughened benzocyclobutene resin and at least about 50% by weight of an inorganic filler. Also electronic packages having at least one conductive layer and at least one layer of the dielectric composite material. The dielectric composite material can have a dielectric constant less than about 3.5, and a dielectric loss of less than about 0.004.

  • Publication number: 20070004844
    Abstract: A composition comprising a mixture of about 9 to about 20 wt % poly(acrylonitrile-co-butadiene) and about 80 to about 91 wt % cyanate ester of the total weight of the poly(acrylonitrile-co-butadiene) and cyanate ester. Also, an article comprising a cured mixture having a continuous phase comprising poly(acrylonitrile-co-butadiene) and a discrete or co-continuous phase comprising cyanate ester.

  • Publication number: 20060103810
    Abstract: A projection engine uses a first polarizing beam splitter (PBS) that substantially reflects light incident along a first input direction in a first polarization state and substantially transmits light incident in the first input direction in a second polarization state orthogonal to the first polarization state. The first PBS demonstrates an angularly dependent reflectivity for light in the second polarization state that is asymmetric about the first input direction. At least two imager devices are positioned to receive light reflected and transmitted by the first PBS respectively. The imager devices modulate the incident light with an image. The image light from the imagers is combined and projected.

  • Publication number: 20060084780
    Abstract: Modified copolyesters having relatively low refractive indices and relatively high glass transition temperatures are disclosed. These modified copolyesters can be used in forming one or more layers in an optical film, such as a multilayer polymer film.
