POLYMER COMPOSITION, MOLDED BODY, AND NERVE REGENERATION INDUCING TUBE
A polymer composition contains polylactic acid and a dilactide/ε-caprolactone copolymer, in which a content of the polylactic acid relative to a total of 100 mass % of the polylactic acid and the dilactide/ε-caprolactone copolymer is 20 to 40 mass %, and in which the dilactide/ε-caprolactone copolym...

| description | A polymer composition contains polylactic acid and a dilactide/ε-caprolactone copolymer, in which a content of the polylactic acid relative to a total of 100 mass % of the polylactic acid and the dilactide/ε-caprolactone copolymer is 20 to 40 mass %, and in which the dilactide/ε-caprolactone copolymer satisfies (1) an R value represented by a following formula is 0.45 or more and 0.99 or less:R=[AB]/(2[A][B])×100where [A] is a molar fraction (%) of a dilactide residue in the dilactide/ε-caprolactone copolymer, [B] is a molar fraction (%) of an ε-caprolactone residue in the dilactide/ε-caprolactone copolymer, and [AB] is a molar fraction (%) of a structure in which a dilactide residue and an ε-caprolactone residue are adjacent to each other (A-B and B-A) in the dilactide/ε-caprolactone copolymer, and (2) at least one of the dilactide residue and the ε-caprolactone residue has a degree of crystallization of less than 14%. |
