    摘要: A crosslinkable composition includes (A) at least one organic compound and (B) at least one linear organosiloxane of general formula. The at least one organic compound is free of siloxane units (=“≡Si—O—Si≡”) and has at least two reactive cyanate ester groups (=“N≡CO—”). The at least one linear organosiloxane is of a general formula RaR1bSiO(4-a-b)/2 (I). The at least one linear organosiloxane consists of three to five units of formula (I).

    摘要: A silsesquioxane of formula: (R1SiO1,5)x(R2SiO1,5)y(R3SiO1,5)z, wherein x≥1, y≥1, z≥1, and x+y+z=6, 8, 10 or 12. R1 is L1-phthalimide, wherein L1 is a residue selected from the group consisting of saturated or unsaturated C1-C8 hydrocarbon radicals which may be straight, branched or cyclic; and substituted or non-substituted arylene; wherein the carbon chains of said residues optionally include one or more of the elements oxygen and nitrogen; and the phthalimide is optionally substituted by one or more halogen, C1-C6 alkyl, —COOH, —OH or —NO2. R2 is a residue selected from the group consisting of saturated or unsaturated C1-C18 hydrocarbon radicals which may be straight, branched or cyclic; wherein the carbon chains of said residues optionally include one or more oxygens and are optionally substituted by one or more halogens. R3 is L2-NH—CO—R4, wherein L2 is a residue selected from the group consisting of saturated or unsaturated C1-C8 hydrocarbon radicals which may be straight, branched or cyclic; and substituted or non-substituted arylene; wherein the carbon chains of said residues optionally include one or more of the elements oxygen and nitrogen; and wherein R4 is a C1-C34 alkyl or a C8-C34 alkene.

    摘要: A side chain type alkyl-modified silicone resin of the present invention is represented by the following general formula (1). In general formula (1), R1 is a hydrogen atom or an alkenyl group, R2 is an alkyl group I having from 1 to 14 carbon atoms, R3 is an alkyl group II having from 15 to 18 carbon atoms, R5 and R6 are each independently a hydrogen atom or a methyl group, R4 is a methyl group or an ethyl group; w, x, y, and z represent the number of units of each structural unit; w, x, y, and z may each be 0; x and y are not 0 at the same time; and a percentage of the sum of x and y with respect to the sum of w, x, y, and z is from 80 to 100%. According to the present invention, a silicone resin can be provided that has high thermal conductivity while maintaining flexibility.
