PURPOSE:The titled composition, containing a specific phosphite compound alone or hindered phenol compound and/or tin compound together, and having improved heat resistance, appearance of molded articles and ability to suppress emission of smell in molding. CONSTITUTION:A polyether ester block copolymer composition obtained by incorporating (A) 100pts.wt. polyether ester block copolymer consisting of 15- 90wt% polyester hard segments and 85-10wt% polyether soft segments having 200-6,000 number-average molecular weight with (B) 0.05-5pts.wt. phosphite compound having >=2 phosphorus atoms in the molecule, e.g. distearylpentaerythritol diphosphite, or (C) 0.05-5pts.wt., preferably 0.1-3pts.wt. hindered phenol compound having preferably >=500mol.wt. and/or (D) 0.001-1pt.wt., preferably 0.01-5pts.wt. tin compound, e.g. monobutyl monohydroxytin oxide. |
