A polymer compound includes a first chain structure constituted by a polyamideimide and a second chain structure constituted by a vinyl polymer and bonded to terminals of the first chain structures and connecting the first chain structures together. The vinyl polymer constituting the second chain structure is a random copolymer including a bond-constituting unit having a side chain to be bonded to the first chain structure, and a non-bond-constituting unit having no side chain to be bonded to the first chain structure.

An electrolytic solution of a nonaqueous electrolyte secondary battery contains a metal salt, and an organic solvent having a heteroatom and satisfies Is&#x3e;Io, when an intensity of an original peak of the solvent is represented as Io and an intensity of a peak resulting from shifting of the original peak is represented as Is. For the negative electrode, (1) a graphite whose G/D ratio of G-band and D-band peaks in a Raman spectrum is not lower than 3.5; (2) a carbon material whose crystallite size, calculated from a half width of a peak appearing at 2&#x3b8;=20 degrees to 30 degrees in a X-ray diffraction profile is not larger than 20 nm; (3) silicon element and/or tin element; (4) a metal oxide configured to occlude and release lithium ions; or (5) a graphite whose ratio (long axis/short axis) is 1 to 5.

Nonaqueous electrolyte secondary battery

To provide a nonaqueous electrolyte secondary battery that suppresses elution of Al from a positive electrode current collector formed of aluminum or an aluminum alloy, and is superior in thermal characteristics and input-output characteristics. Provided is a nonaqueous electrolyte secondary battery including a positive electrode, a negative electrode, and an electrolytic solution. The positive electrode has a positive electrode current collector formed of aluminum or an aluminum alloy. The electrolytic solution contains a metal salt and an organic solvent having a heteroelement. Regarding an intensity of a peak derived from the organic solvent in a vibrational spectroscopy spectrum of the electrolytic solution, Is&#x3e;Io is satisfied when an intensity of an original peak of the organic solvent is represented as Io and an intensity of a peak resulting from shifting of the original peak is represented as Is.

Electrolytic solution

There is provided a process for industrial production of simple 3-carboxy-cis,cis-muconic acid and/or 3-carboxymuconolactone from low molecular mixtures derived from plant components such as vanillin, vanillic acid and protocatechuic acid, via a multistage enzyme reaction. A recombinant plasmid containing a vanillate demethylase gene (vanAB genes), benzaldehyde dehydrogenase gene (ligV gene) and protocatechuate 3,4-dioxygenase gene (pcaHG genes); transformants incorporating the plasmid; and a process for production of 3-carboxy-cis,cis-muconic acid and/or 3-carboxymuconolactone characterized by culturing the transformants in the presence of vanillin, vanillic acid, protocatechuic acid or a mixture of two or more thereof.
