<P>PROBLEM TO BE SOLVED: To provide a biodegradable bio-absorbable material for clinical practice having excellent degradation profiles, heat resistance and a mechanical property. <P>SOLUTION: This biodegradable bio-absorbable material for clinical practice is a polymer blend of A-type polymer (1) and B-type polymer (2). In the formulas of the A-type polymer and B-type polymer, X<SB>1</SB>and X<SB>2</SB>are in the range of 0 to 50 mole%, Y<SB>1</SB>and Y<SB>2</SB>are in the range of 0 to 50 mole%, Z<SB>1</SB>and Z<SB>2</SB>are in the range of 50 to 100 mole%, m<SB>1</SB>and m<SB>2</SB>are in the range of 3 to 8, R<SB>1</SB>and R<SB>3</SB>are the hydrogen or 1-4C alkyl group, R<SB>1</SB>' and R<SB>3</SB>' are the 1-2C alkyl group, and R<SB>2</SB>, R<SB>2</SB>', R<SB>4</SB>and R<SB>4</SB>' are the 1-4C alkyl group, and X<SB>1</SB>and X<SB>2</SB>are not 0 mole% at the same time. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
