Abstract
Abstract One class of organosilicon materials are provided having chemically combined UNITS, WHERE R'''' is a divalent hydrocarbon radical and Q is a radical selected from aryloxyaryl, arylthioaryl, arylsulfonylaryl, and certain heteroaromatic radicals. In addition, organosilicon polymers and copolymers are provided having chemically combined UNITS, WHERE Q'' is a radical selected from Q radicals, monovalent aromatic hydrocarbon radicals and halogenated monovalent aromatic hydrocarbon radicals. The monomers and polymers can be employed as perfume oil bases, in cosmetics and as fluids in the manufacture of elastomers and resins.
