  • Epoxy-modified silicone resin, making method, curable composition, and electronic part
    Patent number: 9896550
    Abstract: An epoxy-modified silicone resin obtained using a compound having 3 or 4 glycidyl groups and 3 or 4 (meth)allyl groups in the molecule is novel. A curable composition comprising the epoxy-modified silicone resin cures into a film having improved heat resistance and adhesion.
    Type: Grant
    Filed: January 4, 2017
    Date of Patent: February 20, 2018
    Assignee: SHIN-ETSU CHEMICAL CO., LTD.
    Inventors: Kazuhide Yanaizumi, Hideyoshi Yanagisawa
  • Aryl compound and making method
    Patent number: 9840484
    Abstract: An aryl compound terminated with at least three glycidyl groups and at least three (meth)allyl groups, having formula (1) wherein R1 is a C3-C20 hydrocarbon, R2 is hydrogen or methyl, and n is 3 or 4 is novel. It is prepared by reacting an aryl compound having at least three (meth)allyl-containing phenol groups with a 2-halomethyloxirane.

  • READILY SINTERABLE SILICON CARBIDE POWDER AND SILICON CARBIDE CERAMIC SINTERED BODY
    Publication number: 20130323152
    Abstract: Provided are: a readily sinterable silicon carbide powder substantially having a stoichiometric composition and from which a dense sintered body can be obtained; a silicon carbide ceramic sintered body having a low specific resistance; and a production method thereof. This readily sinterable silicon carbide powder has a carbon/silicon elemental ratio of 0.96 to 1.04, an average particle diameter of 1.0 to 100 ?m, and a ratio of 20% or less of an integrated value of an absorption intensity in a chemical shift range of 0 to 30 ppm to an integrated value of an absorption intensity in a chemical shift range of 0 to 170 ppm, in a 13C-NMR spectrum. By sintering this silicon carbide powder under pressure, there can be produced a dense sintered body having a low specific resistance and a high purity.
