<p>Title: LIQUID CRYSTALLINE ORGANOSILICON COMPOUNDS Non-crosslinked, branched liquid crystalline organosilicon compounds exhibit the general formula (R3SiO1/2)w (R2SiO)x (RSiO3/2)y (SiO4/2)z where at least one R represents a mesogenic (liquid crystal forming) group, the remaining R represent monovalent hydrocarbon or halohydrocarbon radicals, w represents an integer having a value of at least 1, x, y, and z individually represent an integer including zero, the sum of x and y is at least 1 and the sum of w, x, y, and z is from 4 to 50, inclusive. These liquid crystalline organosilicon compounds exhibit rapidly reversible liquid crystal phase transition over a wide and relatively low temperature range.</p> |
