摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide a composition capable of forming a urethane elastomer having both a low initial modulus and high elongation properties, and good low-temperature characteristics, and its manufacturing method.
SOLUTION: The composition comprises a main agent containing an isocyanate group-terminated prepolymer to be obtained by reacting 1, 2-bis(2-isocyanatoethoxy)ethane with a long-chain polyol and a curing agent containing an active hydrogen compound having an average functional group number of 2-4. The manufacturing method comprises a step of reacting 1, 2-bis(2-isocyanatoethoxy)ethane with a long-chain polyol to prepare an isocyanate group-terminated prepolymer and a step of reacting the obtained isocyanate group-terminated prepolymer with an active hydrogen compound having an average functional group number of 2-4.
