PROBLEM TO BE SOLVED: To provide a method of manufacturing a polyether polyamide resin having little variation of physical properties, excellent tensile elongation at break, and little odor and coloration.SOLUTION: A method of manufacturing a polyether polyamide resin by melting polycondensation of (A-1) a polyether diamine compound represented by the general formula (1), (A-2) a diamine compound other than (A-1) and (B) a α,ω-linear aliphatic dicarboxylic acid compound having 4 to 20 carbon atoms includes the process (1) and the process (2). Process (1): a process of mixing, heating and meting polymerizing the polyether diamine compound (A-1) and the α,ω-linear aliphatic dicarboxylic acid compound (B). Process 2: a process of adding the diamine compound (A-2) to the molten mixture obtained in the process (1). (I), where x+z represents 1 to 60, y represents 1 to 50, and Rrepresents a propylene group. |
