ABSTRACT:
Liquid-crystalline polyorganosiloxanes containing methacryloxy and/or acryloxy groups are prepared by reaction of polyorganosiloxanes containing hydrogen atoms bonded directly to silicon atoms with alkenes and/or alkynes containing mesogenic groups in two steps, wherein the polyorganosiloxanes mentioned are reacted in a first step with alkene and/or alkyne containing mesogenic groups and are reacted in a second step with an alkene and/or alkyne containing at least one methacryloxy and/or acryloxy group and mesogenic groups.
