The present invention relates to liquid-crystalline compounds and to a process for preparing liquid-crystalline polyorganosiloxanes having methacryloxy and/or acryloxy groups by the reaction of organosiloxanes having hydrogen atoms bonded directly to silicon atoms and/or organosilanes which can be condensed to form organosiloxanes having hydrogen atoms bonded directly to silicon atoms, with alkenes and/or alines having mesogenic groups, which comprises reacting in a first step the organosiloxanes with an alkene and/or alkyne having at least one non-enolic hydroxyl group protected by a protective group, and in a second step the protective group is removed and the hydroxyl group which is now free is esterified with (meth)acrylic acid, esters, anhydrides and/or halides thereof and thereafter optionally condensing the organosilanes to organosiloxanes.
