Biodegradable bio-absorbable material for clinical practice

摘要

The object of the present invention is to provide a biodegradable bio-absorbable material for clinical practice having excellent degradation profiles, heat resistance and a mechanical property. The present invention provides a biodegradable bio-absorbable material for clinical practice, which comprises the following A-type polymer and B-type polymer: wherein X₁ and X₂ are in the range of 0 to 50 mole %, Y₁ and Y₂ are in the range of 0 to 50 mole %, Z₁ and Z₂ are in the range of 50 to 100 mole %, m₁ and m₂ are in the range of 3 to 8, R₁ and R₃ are the hydrogen or C1-4 alkyl group, R₁' and R₃' are the C1-2 alkyl group, and R₂, R₂', R₄ and R₄' are the C1-4 alkyl group provided that Y₁ is 0 mole % when X₁ is 0 mole %, Y₂ is 0 mole % when X₂ is 0 mole %, and X₁ and X₂ are not 0 mole % at the same time.
