  • Patent number: 10487406
    Abstract: The disclosure provides compositions and methods for inhibiting corrosion of a copper surface using a bis-imidazoline compound having an aromatic group, such as an aryl bis-imidazoline. The bis-imidazoline corrosion inhibitor can provide one or more advantage in use such as synergistic performance in aqueous and acidic media at low active dosages, resistance to decomposition or degradation in the presence of harsh reagents, ease of dispersion in an aqueous system, and improved thermal stability over conventional triazole based inhibitors. The disclosure also provides methods for the synthesis of bis-imidazoline compounds.

  • Publication number: 20130248833
    Abstract: The invention provides methods for making and using end-functionalized conjugated polymers. Embodiments of the invention comprise performing a coupling polymerization in the presence of AA monomers, BB monomers and an end capping compound that can react with a monomer and which is selected to include a functional group. The functional end groups can, for example, comprise polymers or small molecules selected for their ability to produce conjugated polymers that self-assemble into thermodynamically ordered structures. In certain embodiments of the invention, nano-scale morphology of such conjugated polymer compositions can be driven by the phase separation of two covalently bound polymer blocks. These features make the use of conjugated polymers an appealing strategy for exerting control over active layer morphology in semiconducting polymer materials systems.
