The first aspect of the present invention, referred to as "present invention III", relates to a polyester block copolymer composition (R) obtained by thermally-processing a polyester block copolymer composition (Q) obtained by melt-mixing 100 parts by weight of a polyester block copolymer (P) with 0.1-5 parts by weight of an epoxy compound (C) having one or more epoxy groups under an inert gas atmosphere and not less than 120°C in a solid phase, and further, at a temperature lower than a melting point of the polyester block copolymer composition (R).
The second aspect of the present invention, referred to as "present invention IV", relates to a polyester block copolymer composition which comprises thermally-kneading 0.5-5.0 parts by weight of a mono or morefunctional epoxy compound (C) and 0.01-3.0 parts by weight of a complex-formable agent for a metal (G) such as an oxalic acid derivative and a salicylic acid derivative or a hydrazide derivative with 100 parts by weight of a polyester block copolymer (P1) obtained by a reaction of a crystalline aromatic polyester (A1) with lactones (B).
The third aspect of the present invention, referred to as "present invention V", relates to a polyester block copolymer composition which comprises, in obtaining the polyester block copolymer composition by allowing to react the crystalline aromatic polyester (A1) with lactones (B), adding and thermally-kneading 0.5-5.0 parts by weight of an epoxy compound (C) having one or more pieces of epoxy groups (including at least 0.2 part by weight of two or more functional epoxy compound) and, optionally, 0-2.0 parts by weight of a carbodiimide compound (E) to 100 parts by weight of a polyester block copolymer (P3) obtained by allowing to react 0.1-100% by mol of at least one of a multifunctional compound (D) having at least three pieces of at least one kind of carboxylic group (i), hydroxyl group (ii), and/or an ester-formable group therefrom (iii) with 100% by mol of a crystalline aromatic polyester (A1).
The fourth aspect of the present invention, referred to as "present invention VI", relates to a polyester block copolymer composition which comprises, in obtaining said polyester block copolymer composition by allowing to react the crystalline aromatic polyester (A1) with lactones (B), adding and thermally-kneading 0.1-5.0 parts by weight of an epoxy compound (C) having one or more pieces of epoxy groups and 0-2.0 parts by weight of a carbodiimide compound (E) to 100 parts by weight of a polyester block copolymer (P3) obtained by allowing to react 0.1-200% by mol of at least one of an aliphatic or aromatic multifunctional compound (D) having at least three pieces of carboxylic group (i), hydroxyl group (ii), and/or an ester-formable group therefrom (iii) with 100% by mol of a crystalline aromatic polyester (A1).
The fifth aspect of the present invention, referred to as "present invention VII", relates to a polyester block copolymer composition (R) which comprises, in obtaining the polyester block copolymer composition by allowing to react the crystalline aromatic polyester (A1) with lactones (B), heating a polyester block copolymer composition (Q) at a solid phase, and the composition (Q) is obtained by adding and thermally-kneading 0.1-5.0 parts by weight of at least one kind of an epoxy compound (C) having one or more pieces of epoxy groups to 100 parts by weight of a polyester block copolymer (P) obtained by allowing to react 0.1-200% by mol of at least one of a multifunctional compound (D) having at least three pieces of carboxylic group (i), hydroxyl group (ii), and/or an ester-formable group therefrom (iii) with 100% by mol of a crystalline aromatic polyester (A1).
