  • Patent number: 6476113
    Abstract: Thermosetting and thermoplastic elastomers are provided having magnetic filler packed within the elastomeric matrix and capable of being aligned and energized, before, during or after the molding of the elastomer. The magnetically-filled elastomers therefore provide useful permanent magnetic fields which being physically soft. The magnetic filler is aligned within the elastomeric matrix and energized by subjecting the magnetically-filled elastomer to magnetic energy before, during and/or after molding of the magnetically-filled elastomer. A particularly preferred magnetically-filled elastomer is a magnetically-filled polyurethane elastomer composition wherein the elastomer is the reaction product of a urethane-forming compound having at least two urethane-forming reactive sites, an elasticizing diol or triol, and a diisocyanate reacted in less than stoiciometric amounts to allow for the formation of urethane linkages involving less than about 85% of the urethane-forming reactive sites.

  • Patent number: 6359048
    Abstract: By combining alkali earth oxide aluminate phosphors with an alkyd base, a rheology improver, another pigment, an anti-skin additive, and other ingredients, one can achieve a luminescent paint that has characteristics including tintability, applicability, viscosity, appearance and coloration comparable to a non-luminescent paint, with adequate protection from moisture and at a relatively reasonable cost. An alkyd base formulation is the preferred formulation that will allow for the highest amount of loading without compromising the quality of the paint with respect to appearance or applicability. The appearance of the paint in daylight has minimal orange peel or pockmark affects because of the ability of this formulation to suspend and diffuse the large luminescent particles effectively while applying the product. In addition because of the effectiveness of this formulation the appearance of the glow is even, consistent and undisrupted in a properly installed scenario.

    Abstract: A thermoplastic polymer having a carbonyl-containing group and a nitrogen-containing 5-membered heterocycle-containing group in side chains, and a composition thereof. The thermoplastic polymer and composition thereof have excellent recycle property in that physical properties do not deteriorate even though formation of crosslinking and dissociation of crosslinking are repeatedly conducted with altering temperature. The thermoplastic polymer and composition thereof are that its crosslinked structure is considerably stable at room temperature, and therefore have considerably high tensile strength. In particular, in the case of bonding to a main chain at 3-position or 4-position of a nitrogen-containing 5-membered heterocycle, intermolecular hydrogen bond is caused, so that a cured product has high mechanical properties.

In particular, it has been discovered that 5 weight percent Co(II) acac can increase the dielectric constant of DER661 epoxy by about 60%. 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.
