摘要: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, Ar 1 is a residue from the dichloroaromatic compound, Ar 2 is a residue from the dihydroxyaromatic compound, and n is a non-negative integer.

摘要:The invention comprises a networked polymer comprising the formula: n wherein n≧1; wherein n is an average value obtained by averaging all repeating units of the networked polymer; wherein m≧1; wherein Y is a divalent group containing one or more acetylenic groups, one or more crosslinks, or both; n wherein z is the average number of crosslinks per Y group; wherein Ar 1 and Ar 2 are independently selected aromatic groups; and wherein each R is independently selected from the group consisting of alkyl, aryl, alkylaryl, haloalkyl, haloaryl, and combinations thereof. The invention also includes prepolymers and precursors needed to make the networked polymer and processes for making all of the above. The invention also includes a ceramic composition made by pyrolysis of the networked polymer.
