ABSTRACT:
New polyquinoline polymers are provided, as well as new methods for preparing the polyquinoline polymers using a novel combination of monomers. The polyquinoline polymers comprise repeat units comprising at least one quinoline nucleus and at least one ether linkage and having as end groups either fluoro groups or hydroxy groups or a combination of fluoro and hydroxy groups. The polymers are formed by providing a monomer comprising two fluoro groups, where each such fluoro group is activated by a quinoline nucleus, a diol monomer provided in the form of its bis-oxide salt, or in the presence of a base capable of deprotonating the diol and reacting the difluoro and diol monomers together in a dipolar solvent to form the polyquinoline polymer. In an alternative embodiment, the polyquinoline polymers of the present invention are formed by reacting a fluoro hydroxy monomer comprising a quinoline nucleus containing one activated fluoro group and one hydroxy group in the presence of a base and a dipolar solvent to form said polymer. In yet another alternative embodiment, the polyquinoline polymer is formed by providing a monomer which comprises a quinoline nucleus containing one activated fluoro group and one hydroxy group and treating the monomer with a base to form an oxide salt and reacting the monomer salt in a dipolar solvent to form said polymer.
