摘要：At least one (poly)thio alkoxy and/or halosilane is/are prepared by reaction of at least one sulfur-containing reagent with at least one alkoxy and/or halosilane, wherein an ionic addition of a sulfur-containing reagent to an alkoxy and/or halosilane is preferably conducted with thermal and/or actinic activation; the novel polythio alkoxy and/or halosilanes of formula (III.2) thus prepared are particularly useful as coupling agents in elastomeric compositions containing a white filler of the silica type and having the formula (III.2) wherein, for example, R1.1 and R1.3=methyl and R1.2=ethoxy.
