(In the above formula (I), R is a terephthalic acid or its lower alkyl ester alone or aromatic dicarboxylic acid such as isophthalic acid, old phthalic acid, naphthalenedicarboxylic acid form, adipic acid, sebacic acid, dimer acid, etc. A mixture with an aliphatic dicarboxylic acid such as aliphatic dicarboxylic acid or cyclohexanedicarboxylic acid such as a form may be used, and D is an aliphatic glycol component having 2 to 8 carbon atoms, mainly 1,4-butanediol Ethylene glycol, 1,2- or 1,3-propylrel glycol, 1,5-pentanediol, 1,6-hexanediol, 1,4-cyclohexanedimethane, and the like may be used herein. In Formula (II), R is the same as in Formula (I), and G is a polyalkylene oxide glycol component having a molecular weight of 300 to 6000. Poly (tetramethylene oxide) glycol is mainly used. , Here polyethylene A recall or polypropylene glycol can be used alone or in a mixture form.)

B) The polyether ester block copolymer resin composition formed by melt-mixing the cyclic imino ether compound represented by following structural formula (III).

(In the above formula (III), X is a divalent substrate having no reactivity with the polyether ester block copolymer, and has 2 to 10 carbon atoms such as ethylene, propylene, pentylene, hexamethylene, octamethylene, nonamethylene and decamethylene Aliphatic components, aromatic components such as phenylene, naphthylene, biphenylene, or alicyclic components such as cyclohexylene, cyclohexanedimethylene, and the like.

A and B may be components such as methylene, ethylene, propylene or butylene, and A and B may have the same or different structures.)
