| titleOfInvention | Method for producing polyurethane solution |
| abstract | (57) [Abstract] [PROBLEMS] The present invention provides a method for producing a polyurethane solution capable of producing a polyurethane elastic yarn having excellent physical properties and having a small amount of residual solvent by high-speed spinning. . [Structure] When carrying out a chain extension reaction of a prepolymer with an organic diamine so that the concentration of the polyurethane solution is increased and the polymer molecular weight is reduced to maintain the fluidity of the solution, and the polymer is polymerized by heat treatment. By using the secondary monoamine and the ketoimine amine and / or the aldimine amine as the end-stopping agent in combination, a polyurethane elastic yarn having excellent physical properties and a small amount of solvent remaining can be produced by high-speed spinning. |
