Conjugated Polymers for Corrosion Inhibition

Spectra Group Limited's (SGL) contribution in responding to N00-079 is the development of an improved, benign, cost effectivesynthesis of poly[2,5-bis(N-methyl-N-alkylamino)phenylenevinylene] and several of its analogs. Replacing the low yieldingpolymerization step in the current synthesis is the one of themain objectives of this proposal as is continuing to replace anytoxic reagents still being used. Once the synthesis of theaforementioned PPV is complete, the major effort will be directedtowards synthesizing analogs on kilogram scale. Once thesedifferent PPVs have been assembled, experiments will be conductedto determine which of them meet the proper criteria for corrosioninhibition.BENEFITS: The anticipated benefit of this proposal is the development of a benign cost effective synthesis that can readily be scaled up to acommercial level. The ready availability of conjugated polymers would be of significant interest to the public and private sector.
