NRL

A compound having the formula: Each Ar is an aromatic group. Each R is an alkyl group. The value n is a positive integer. The values of w, x, y, and z are 0 or 1. If y is 0 than x and z are 0 and w is 1, and if y is 1 than x and z have different values and w equals z. A thermoset made by crosslinking a silane-containing compound with the above compound. A method of making the above compound when y is 1 by: reacting 4,4′-difluorobenzophenone with an aromatic diol to form an oligomer; and reacting the oligomer with a vinyl dialkylsilane. A method of making the below compound by: reacting 4,4′-difluorobenzophenone with a vinyl dialkylsilane. Each R is an independently selected alkyl group.
