THE INVENTION PROVIDES MERCAPTOSILANES OF THE GENERAL FORMULA I WHEREIN R1 IS AN ALKYL POLYETHER GROUP -O-(R5-O) M-R6. THEY ARE PREPARED BY A PROCEDURE IN WHICH A SILANE OF THE GENERAL FORMULA II IS SUBJECTED TO A CATALYSED REACTION WITH AN ALKYL POLYETHER R1-H, R7-OH BEING SPLITOFF, THE MOLAR RATIO OF THE ALKYL POLYETHERS R1-H TO THE SILANE OF THE GENERAL FORMULA II IS AT LEAST 0.5 AND R7-OH IS SEPARATED OFF FROM THE REACTION MIXTURE CONTINUOUSLY OR DISCONTINUOUSLY. THEY CAN BE USED IN SHAPED ARTICLES. |
