    Abstract: PROBLEM TO BE SOLVED: To provide a method of decomposition treating a polymeric MDI-based polyurea compound by which a reusable polymethylene polyphenyl polyamine (PMDA) is recovered without adding any hydrolysis accelerator such as an alkali to a polyurea residue, produced as a by-product in the manufacture of polymethylene polyphenylene polyisocyanate (polymeric MDI), for which there has been no other choice but to be disposed of, and which does not bring about any corrosion problem of a reactor. SOLUTION: In the method of decomposition treating the polymeric MDI-based polyurea compound, the polymeric MDI-based polyurea compound is hydrolyzed in carbon dioxide in a supercritical or subcritical state.

    Abstract: PROBLEM TO BE SOLVED: To provide a polyurea electrolyte suitable for an electrolyte membrane for a fuel cell and excellent in mechanical strength and acid resistance.
    SOLUTION: The polyurea electrolyte includes a polyurea resin formed by polymerizing a first compound having two or more isocyanate groups and a second compound having two or more amino groups. The polyurea electrolyte is characterized in that the first compound or the second compound contains ten or more carbon chains, and in that the first compound or the second compound contains a sulfonic acid group or a carboxylic acid group. Further, the production method for the polyurea electrolyte is characterized by including a step of neutralizing the sulfonic acid group or the carboxylic acid group in the first compound or the second compound using a neutralizer, a step of polymerizing the first compound and the second compound following the neutralization step, and a step of removing the neutralizer from the polymer of the first compound and the second compound following the polymerization step.
