Abstract: PROBLEM TO BE SOLVED: To provide a polyester block copolymer composition having a good moldability applicable without difficulty to various molding processes such as blow molding, good thermal resistance and rubber-like elasticity. SOLUTION: Crystalline aromatic polyesters and lactones are reacted to form polyester block copolymers, where at least one of polyfunctional compounds having three or more of carboxyl groups, hydroxyl groups and/or their eater forming groups in a molecule is added in 0.1 to 200 mole % based on 100 mole % of the crystalline aromatic copolymers. To 100 pts.wt. of the polyester block copolymers, one of epoxy compounds having at least one epoxy group is blended in a range of 0.1 to 5.0 pts.wt. and melt blended and further heated in a solid phase to obtain the polyester block copolymer composition.

Abstract: PROBLEM TO BE SOLVED: To obtain an aliphatic polyester having controlled thermal decomposition property, hydrolyzability and biodegradability without varying various other physical properties. SOLUTION: An aliphatic polyester is produced by the ring-opening polymerization of a lactone (e.g. ε-caprolactone) or a lactide (e.g. lactic acid) using a high-boiling monoalcohol (e.g. hexanol) or a metal alkoxide (e.g. an aluminum alkoxide) as an initiator to decrease the contents of alcohol terminal and carboxylic acid terminal to

Abstract: PROBLEM TO BE SOLVED: To provide a method in which a polyester block copolymer of fixed quality can be produced efficiently and industrially by reacting a crystalline aromatic polyester with lactones.
SOLUTION: The method comprises feeding continuously a molten crystalline aromatic polyester (A) with a gear pump and a lactone (B1) or a lactone composition (B2) with a metering pump into a static mixer at constant rates respectively to make both react with each other and thus form a polyester block copolymer. In this process, it is preferable that the crystalline aromatic polyester (A) may be fed in such a way as to give inlet-side pressure of the gear pump of 0.0098 MPa or above (gauze pressure). Further, the charging pressure of the lactone (B1) or the lactone composition (B2) is preferably controlled to be 1.96 MPa or above (gauze pressure).

Abstract: PROBLEM TO BE SOLVED: To stably produce a lactide-lactone copolymer excellent in heat resistance and impact resistance at a low cost by regulating the average chain length of the lactide-lactone copolymer so as to be within a specific range. SOLUTION: A remaining lactide (e.g. L-lactide) is added to a product during the polymerization or after finishing the polymerization of 2-85% lactide of the total lactide with a lactone (e.g. ε-caprolactone), and further polymerized to provide the objective lactide-lactone copolymer having >=3 (average) chain length of lactide units and 1-10 chain length of lactone units. The lactide units comprise random parts having =5 chain lengths, and the chain length 1LL(B) of the block part satisfies the inequality 1LL (B)2>[fL/(fL+fCap)]3×23 (fL is a lactone composition in the copolymer; fCap is a lactide composition).
