  • Publication number: 20240082457
    Abstract: A hard tissue repair adhesive composition and a hard tissue repair kit comprising same. The adhesive composition comprises a polymerizable monomer (A), polymer powder (B), a polymerization initiator (C), and a filler (D). The polymerization initiator (C) comprises 100 parts by weight of alkoxydialkylboron having a purity of 97% or more and 0.2-5 parts by weight of an alcohol having a boiling point of 60° C. to 180° C. The polymerization initiator (C) does not generate smoke or coking or present ignition quality even when in contact with paper, porous fibers or the like in air, is easy to be taken in a small amount, and can provide a polymerizable composition with high polymerization activity, thereby providing an adhesive composition suitable for hard tissue repair. (A), (B), (C), (D) and all other components comprised according to requirements of the adhesive composition for hard tissue repair can be separately or mixedly stored in three or more members to form a repair kit.

  • Patent number: 8129555
    Abstract: Aminosilane precursors for depositing silicon-containing films, and methods for depositing silicon-containing films from these aminosilane precursors, are described herein. In one embodiment, there is provided an aminosilane precursor for depositing silicon-containing film comprising the following formula (I): (R1R2N)nSiR34-n??(I) wherein substituents R1 and R2 are each independently chosen from an alkyl group comprising from 1 to 20 carbon atoms and an aryl group comprising from 6 to 30 carbon atoms, at least one of substituents R1 and R2 comprises at least one electron withdrawing substituent chosen from F, Cl, Br, I, CN, NO2, PO(OR)2, OR, SO, SO2, SO2R and wherein R in the at least one electron withdrawing substituent is chosen from an alkyl group or an aryl group, R3 is chosen from H, an alkyl group, or an aryl group, and n is a number ranging from 1 to 4.

  • Patent number: 7919409
    Abstract: We have used the state-of-the-art computational chemistry techniques to identify adhesion promoting layer materials that provide good adhesion of copper seed layer to the adhesion promoting layer and the adhesion promoting layer to the barrier layer. We have identified factors responsible for providing good adhesion of copper layer on various metallic surfaces and circumstances under which agglomeration of copper film occur. Several promising adhesion promoting layer materials based on chromium alloys have been predicted to be able to significantly enhance the adhesion of copper films. Chromium containing complexes of a polydentate ?-ketoiminate have been identified as chromium containing precursors to make the alloys with chromium.
