23443-483 Abstract Mixtures of siloxane oligomers are disclosed having a degree of oligomerisation of 0 to 8 and carrying at most one vinyl substituent per silicon atom, as well as methoxy and/or ethoxy groups, the molar ratio of vinyl groups to alkoxy groups being 1:1 to 1:8. Optional alkyl substituents having 1 to 18 C atoms may also be present, the molar ratio of vinyl groups to alkyl groups being 1:0 to 1:8. The mixtures are prepared by hydrolysis or co- hydrolysis of vinyltrialkoxysilanes and optionally tetraalkoxysilanes and alkyltrialkoxysilanes in alcoholic solution in the presence of acid catalysts with an amount of water calculated for the degree of oligomerisation and subsequent removal of the catalyst and of the free alcohols, The mixtures are used as crosslinking agents for thermoplastic polyolefins. They are free of many disadvantages of known crosslinking agents, such as high volatility and toxicity.
