Abstract
A polysiloxane having a refractive index of about 1.56 measured at light wavelength 633 nm, characterized in that the polysiloxane includes siloxane T units of the formula ##STR00001## where A represents an alkylene group having 1 to 4 carbon atoms: n=0 or 1; m is at least 1; and Ar is an aryl group substituted by at least one iodine, bromine or chlorine atom, or is a polynuclear aromatic group. The invention includes chlorosilanes having the formula (Ar) m-(A)nSiCl3, useful in forming high refractive index polysiloxanes.
