Abstract
A method of: providing a solution of: a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; an excess of a dihydroxyaromatic compound; a base; and a solvent; heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form an aromatic ether oligomer; and reacting the aromatic ether oligomer with a chlorodialkylvinylsilane to form one or more vinyl-terminated compounds having the formula below. The aromatic ether oligomer is a dihydroxy-terminated compound or a dimetallic salt thereof. Water formed during the heating is concurrently distilled from the solution. Each R is an alkyl group, Aris a residue from the dichloroaromatic compound, Aris a residue from the dihydroxyaromatic compound, and n is a non-negative integer.
