Novel liquid crystalline resins based on MQ siloxanes

MQ siloxane resins containing Si–H functions have been made from tetramethyldisiloxane and tetraethoxysilane. Hydrosilylations with mesogenic alkenes give low molecular weight liquid crystal MQ resins with potentially useful properties.

Low molecular weight siloxane polymers with liquid crystal properties may be synthesised by hydrosilylation of mesogenic alkenes with readily available MQ resins containing Si–H bonds; they constitute a new group of versatile materialsFigure optionsDownload as PowerPoint slide
