  • Self-etching emulsion dental compositions and methods
    Publication number: 20050176844
    Abstract: The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effective to etch the dental structure surface.

  • Reactive hydrophilic oligomers
    Publication number: 20050131148
    Abstract: Hydrophilic compositions are described, which are prepared from a first component oligomer containing pendent hydrophilic groups and pendent reactive functional groups capable of reaction at effective rates (at normal processing temperatures), with a co-reactive second component possessing functionality that is complementary to that of the first oligomer. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.

  • Reactive hydrophilic oligomers
    Publication number: 20050070688
    Abstract: Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing polymerizable groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.

  • Organic polymers, laminates, and capacitors
    Publication number: 20050019592
    Abstract: Organic polymers for use in laminates including capacitors, wherein the polymer includes repeat units of the formula: wherein: each R1 is independently H, an aryl group, Cl, Br, I, or an organic group that includes a crosslinkable group; each R2 is independently H, an aryl group or R4; each R3 is independently H or methyl; each R5 is independently an alkyl group, a halogen, or R4; each R4 is independently an organic group that includes at least one CN group and has a molecular weight of about 30 to about 200 per CN group; and n=0-3; with the proviso that at least one repeat unit in the polymer includes an R4.
