The invention relates to a composition for use in a monosil process for crosslinking thermoplastic polyolefins, comprising (i) a content of capryl acid (H3C(CH2)6COOH) of 5 to 60 wt.%, (ii) a content of at least one monounsaturated organofunctional alkoxysilane of the general formula: A-SiR2 x(OR1)3-x (I), in which R1 represents independently of one another a linear or branched hydrocarbon group with 1 to 4 C atoms, R2 represents methyl, x equals 0, and A stands for a monovalent olefin group of the formula (R3)2C=C(R3)-Mk-, where k equals 0, groups of R3 are the same or different, R3 is a hydrogen atom or a methyl group, and the group M corresponds to a group of the series -CH2-, -(CH2)2-, -(CH2)3-, or -C(O)O-(CH2)3-, (iii) a content of at least one radical former, and (iv) optionally a content of at least one other component, all components (i) to (iv) equaling a sum of 100 wt.%. The invention further relates to a production method and thermoplastic polyolefin-based molded bodies or products which can be obtained using said method, wherein a composition according to the invention is reacted together with at least one thermoplastic polyolefin in a monosil process. The invention further relates to the use of a composition according to the invention for use in the monosil process for crosslinking thermoplastic polyolefins in the production of thermoplastic polyolefin-based products formed by means of extrusion. |
