| titleOfInvention | Method for the preparation of a polyester block copolymer, a polyester block copolymer composition and method for the preparation thereof |
| abstract | The first aspect of the present invention, referred to as "presentninvention III", relates to a polyester block copolymer composition (R)nobtained by thermally-processing a polyester block copolymer compositionn(Q) obtained by melt-mixing 100 parts by weight of a polyester blockncopolymer (P) with 0.1-5 parts by weight of an epoxy compound (C)nhaving one or more epoxy groups under an inert gas atmosphere and notnless than 120°C in a solid phase, and further, at a temperature lower thanna melting point of the polyester block copolymer composition (R). n The second aspect of the present invention, referred to as "presentninvention IV", relates to a polyester block copolymer composition whichncomprises thermally-kneading 0.5-5.0 parts by weight of a mono ornmorefunctional epoxy compound (C) and 0.01-3.0 parts by weight of ancomplex-formable agent for a metal (G) such as an oxalic acid derivativenand a salicylic acid derivative or a hydrazide derivative with 100 parts bynweight of a polyester block copolymer (P1) obtained by a reaction of ancrystalline aromatic polyester (A1) with lactones (B). n The third aspect of the present invention, referred to as "presentninvention V", relates to a polyester block copolymer composition whichncomprises, in obtaining the polyester block copolymer composition bynallowing to react the crystalline aromatic polyester (A1) with lactones (B),nadding and thermally-kneading 0.5-5.0 parts by weight of an epoxyncompound (C) having one or more pieces of epoxy groups (including atnleast 0.2 part by weight of two or more functional epoxy compound) and,noptionally, 0-2.0 parts by weight of a carbodiimide compound (E) to 100nparts by weight of a polyester block copolymer (P3) obtained by allowing nto react 0.1-100% by mol of at least one of a multifunctional compoundn(D) having at least three pieces of at least one kind of carboxylic group (i),nhydroxyl group (ii), and/or an ester-formable group therefrom (iii) withn100% by mol of a crystalline aromatic polyester (A1). n The fourth aspect of the present invention, referred to as "presentninvention VI", relates to a polyester block copolymer composition whichncomprises, in obtaining said polyester block copolymer composition bynallowing to react the crystalline aromatic polyester (A1) with lactones (B),nadding and thermally-kneading 0.1-5.0 parts by weight of an epoxyncompound (C) having one or more pieces of epoxy groups and 0-2.0 partsnby weight of a carbodiimide compound (E) to 100 parts by weight of anpolyester block copolymer (P3) obtained by allowing to react 0.1-200% bynmol of at least one of an aliphatic or aromatic multifunctional compoundn(D) having at least three pieces of carboxylic group (i), hydroxyl group (ii),nand/or an ester-formable group therefrom (iii) with 100% by mol of ancrystalline aromatic polyester (A1). n The fifth aspect of the present invention, referred to as "presentninvention VII", relates to a polyester block copolymer composition (R)nwhich comprises, in obtaining the polyester block copolymer compositionnby allowing to react the crystalline aromatic polyester (A1) with lactonesn(B), heating a polyester block copolymer composition (Q) at a solid phase,nand the composition (Q) is obtained by adding and thermally-kneadingn0.1-5.0 parts by weight of at least one kind of an epoxy compound (C)nhaving one or more pieces of epoxy groups to 100 parts by weight of anpolyester block copolymer (P) obtained by allowing to react 0.1-200% bynmol of at least one of a multifunctional compound (D) having at least nthree pieces of carboxylic group (i), hydroxyl group (ii), and/or an ester-formablengroup therefrom (iii) with 100% by mol of a crystalline aromaticnpolyester (A1). |
