<p><P>PROBLEM TO BE SOLVED: To provide a novel method for producing a polyurea, wherein carbon dioxide is introduced while a diamine compound and water coexist with each other and polymerization of the polyurea is carried out at a pressure of 0.1-7 MPa by using the carbon dioxide. <P>SOLUTION: In the method for producing polyurea, carbon dioxide is introduced while the diamine compound and water coexist with each other, and polymerization of the polyurea is carried out at a pressure of 0.1-7 MPa. In this method, 100 mol% of the diamine compound coexists with 50 mol% or more of water. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
