Abstract
What is disclosed and claimed are organopolysiloxanes having liquid crystalline properties at relatively low temperatures as compared to prior art materials. The organopolysiloxanes have this property by virtue of a unique chemical spacer between the siloxane and the mesogenic groups, which spacers are oxyalkylene groups.
