    摘要: A three-stage process for the continuous preparation of RTV-1 compositions comprises, in a first step, preparing a raw mixture of &agr;,&ohgr;-dihydroxypolydiorganosiloxane, filler and, if desired, further constituents, in a second step, freeing the raw mixture of gas inclusions under reduced pressure and, if desired, mixing it with further constituents and, in a third step, mixing the degassed raw mixture with a crosslinker, a condensation catalyst and, if desired, additional constituents not yet added in the first and second steps.
