mechanically strong absorbable polymer blend compositions with precisely controllable absorption rates, processing methods, and products thereof

摘要

Patent Summary: "Mechanically strong absorbable polymer blend compositions with precisely controllable absorption rates, processing methods, and products thereof". The present invention relates to novel absorbable polymer blends. Blends are useful for the manufacture of medical devices having manipulated degradation and retention of breaking strength in vivo. The blends consist of a first absorbable polymer component and a second absorbable polymer component. The weight average molecular weight of the first polymer component is higher than the weight average molecular weight of the second polymer component. at least one of said components has the chain terminus at least partially blocked by a carboxylic acid group. Additional aspects are medical devices produced from this.
