The mechanical properties and degradable properties of PLA PEG/PU elastomers were determined by DMA
stress strain and degradable experiment.The result shows that the tensile strength and the elongation decreased
as the content and the Mw of PEG increased.The degradable time increased with the Mw of PEG increased
but decreased with the content of PEG increased.The elastomer was degraded mainly from the surface
but sometime faster in the inner in urine.There was an auto- acceleration effect in the degrading process of PLA-PEG/PU elastomer.The animal experimental result shows that the elastomer is fit to Urethra-Supporting.
