摘要:
A bone cement comprises a powdery component including calcium phosphate and an aqueous liquid component. A radiopaque material is added to at least one of the powder and liquid components, and the components may be combined into a pasty substance for application to bone.
摘要:
The present invention is a tinted, optical adhesive for use in making plasma display filters comprising a substantially acid free, pressure-sensitive adhesive (PSA) containing a narrow-band, visible spectrum dye (e.g. less than 30 nm bandwidth) and a broader-band, near infra-red spectrum dye (e.g. greater than 200 nm), the second dye providing enhanced thermal stability as well as near infra-red (NIR) blocking. Further, acid-free adhesives offer improved stability of light control dyes. In the present invention, porphyrin-based dyes combined with acrylate-based, pressure-sensitive optical adhesives are preferred. Invention offers reduced number of functional layers in an optical filter structure as well as reduced number of manufacturing (lamination) steps in the optical filter/plasma display assembly process.
摘要:
Reactive systems for polymerizing ethylenically unsaturated compounds comprising a first component, comprised of ethylenically unsaturated compounds capable of polymerization, and a second component of a hardener system comprised of organoboron compounds which are stabilized with suitable oligomers. An organic peroxide (perester, hydroperoxide, perether and/or peranhydride)is admixed with the compounds. These components are mixed to form a polymer. The reactive system reaches full strength in reduced time with the use of the organic peroxide and are suitable for joining hard body materials in human or animal tissue, in particular in the surgical and/or dental sector, in the production of body-absorbable or body-resistant adhesives, cements, and/or filling compounds and for forming synthetic material moldings.
摘要:
The present invention relates to improved bone sealants for staunching local haemorrhages on bones, which are characterized in that the bone sealant consists of a polyester oligomer synthesized from polyol, lactide and glycolide, and water-soulble polymers.
