摘要 |
Absorbable, multiphasic, crystalline, solid blend compositions having at least two first order thermal transitions, are formed of a segmented l-lactide copolymer as the principal or major component and at least one additional crystalline thermoplastic absorbable polyester having glycolide-based sequences, a fraction of which participated in ester-ester interchange reactions with lactide-based sequences to produce crystalline materials with modulated properties for use in producing orthopedic and tissue-repair devices.
