摘要： 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.

摘要： Polymerizing cyclic trisiloxanes using as the polymerization initiator an alkali metal salt of an organosilane or organopolysiloxane having a terminal alkenyl group, followed by termination of the reaction, produces an organopolysiloxane having an alkenyl group on one end. These organopolysiloxanes are useful for making copolymers and as additives to siloxane elastomers.

摘要： Polydiorganosiloxanes which have a pendant alkenyl radical in the middle of the molecular chain are prepared by a nonequilibrium, living polymerization of cyclic trisiloxanes using an organopolysiloxane alkali metal salt of the formula ##STR1## where M is lithium, sodium, or potassium, which takes place under substantially anhydrous conditions, and the polymerization is terminated with an end-capping reaction to produce a polydiorganosiloxane of the formula ##STR2## where R.sup.1 is an alkenyl radical. These polymers can be used to make graft copolymers and can be made more functional when the ends are capped with functional groups.
