  • Patent number: 10227434
    Abstract: The invention relates to a composition for use in a Monosil process for the crosslinking of thermoplastic polyolefins which comprises (i) from 5 to 60% by weight content of caprylic acid (H3C(CH2)6COOH), (ii) content of at least one monounsaturated organofunctional alkoxysilane of the general formula I A-SiR2x(OR1)3-x??(I), where R1 is mutually independently a linear or branched hydrocarbon moiety having from 1 to 4 C atoms, R2 is methyl and x is 0 or 1 and A is a monovalent olefin group of the formula (R3)2C?C(R3)-Mk-, where k is 0 or 1, in which groups R3 are identical or different and R3 is a hydrogen atom or a methyl group and the group M is a group from this list: —CH2—, —(CH2)2—, —(CH2)3— and C(O)O—(CH2)3—, (iii) content of at least one free-radical generator and (iv) optionally content of at least one other component, where the entirety of all components (i) to (iv) gives 100% by weight.

  • Patent number: 9273186
    Abstract: The invention relates to a composition containing olefinically functionalized siloxane oligomers which are derived from olefinically functionalized alkoxy silanes and optionally alkoxy silanes functionalized with saturated hydrocarbons and optionally a tetra alkoxysilane, at most comprising an olefinic group on the silicon atom and which has a reduced chloride content and a weight average molecular mass (Mw) of more than 315 g/mol.
