Polyphenylquinoxalines containing pendant phenylethynyl and ethynyl groups

Claim 1

A poly(phenylquinoxaline) polymer consisting essentially of repeating units and synthesized from the reaction of (I) aromatic bis(o-diamines) with (II) aromatic bis(α-diketones) and (III) aromatic bis(ethynylphenyl-α-diketones) or aromatic bis(phenylethynyl-α-diketones) according to the reaction scheme: ##STR12## where Ar is aromatic and selected from the group consisting of ##STR13## Ar' is ##STR14## X is --C.tbd.CH, ##STR15## Y is 5-100% X and 0-95% H, and, n is 20-10,000.

Claim 25

A method of synthesizing novel polymers comprising: combining stoichiometric quantities of a bis(1,2-diketone) monomer in a solvent selected from a group consisting of chloroform, sym-tetrachloroethane, m-cresol, and mixtures of m-cresol and xylene and m-cresol and toluene at a concentration of 10 to 30% weight/volume with powdered 3,3'4,4'-tetraaminobiphenyl stirring the mixture for 4-6 hours at ambient temperature and thereafter stirring for one hour at 90° C. to recover an amber colored viscous solution, doctoring a portion of this solution onto a glass plate and stage drying to a final temperature of approximately 110° C. under vaccum for 4-6 hours to yield a transparent yellow film fingernail creaseable polymer.

Claim 26

A method of synthesizing novel polymers comprising: combining stoichiometric quantities of a bis(1,2-diketone) monomer in a solvent selected from a group consisting of chloroform, sym-tetrachloroethane, m-cresol, and mixtures of m-cresol and xylene and m-cresol and toluene at a concentration of 10 to 30% weight/volume with powdered 3,3'4,4'-tetraaminobiphenyl stirring the mixture for 4-6 hours at ambient temperature and thereafter stirring for one hour at 90° C. to recover an amber colored viscous solution, doctoring a portion of this solution onto a glass plate and stage drying to a final temperature of approximately 110° C. under vaccum for 4-6 hours to yield a transparent yellow film fingernail creaseable polymer.
