    摘要： A cross-linkable composition along with processes for producing the same, uses for the same and articles made therefrom. The cross-linkable composition includes (A) at least one organic compound that is free of siloxane units having at least two reactive cyanate ester groups


    (═“N≡C—O—”) and

    (B) at least one cyclosiloxane having the general formula (I)


    [RaRb1SiO2/2]m   (I).

    Where R may be identical or different and represents monovalent, SiC-bonded, saturated aliphatic hydrocarbon radicals; where R1 may be identical or different and represents monovalent, SiC-bonded, halogen- or phosphorus-substituted, aromatic hydrocarbon radicals; where a is 0, 1 or 2, preferably 0 or 1, particularly preferably 0; where b is 0, 1 or 2, preferably 1 or 2, particularly preferably 2; where m is 3, 4 or 5, preferably 3 or 4, particularly preferably 4; and where a+b is 2 and at least three radicals R1 are present per siloxane molecule (B).

    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).
