Abstract:
A continuous process for the polymer-analogous reaction of organopolysiloxane polymers bearing functional groups with a reactive compound, comprisinga) in a first step, preparing a mixture of the organopolysiloxane polymers bearing functional groups and the reactive compound, b) in a second step, conducting the mixture continuously through a reaction zone and reacting said mixture there, wherein said reaction is a hydrosilylation reaction, and said polyorganosiloxane polymer bears hydrosilylatable unsaturated hydrocarbon groups or â‰¡Siâ€”H groups; wherein said reactive compound contains a â‰¡Siâ€”H group as a reactive group when said organopolysiloxane polymer bears hydrosilylatable unsaturated hydrocarbon groups, and said reactive compound contains a hydrosilylatable unsaturated group as a reactive group when said organopolysiloxane polymer bears â‰¡Siâ€”H groups; and wherein the reaction takes place in the presence of an effective amount of at least one hydrosilylation catalyst.
