Abstract: In this paper,the effects of change of degradable rate and relative molecular mass on the degradable behaviors of four lactide chain-extened polymers are contrasted with those of lactide polymers.The results indicated that the four lactide chain-extened polymers could degrade in this experiment and their degradable rate were lower than that of P-LA.LA-SDI has the highest degradable rates among the four lactide chain-extened polymers,but there was no significant difference among aromatic and aliphatic lactide chain-extened polymers.The results showed that the degradable rates were dependent on experiment methods and condition and also indicated that the relative molecular mass became smaller and smaller with the progress of degradation time.
