RESULTS Degra-dation of PCL was the slowest one.Mass-loss was not obvi-ous:molecular mass of pancreatic suspension lost by19.8%and no outstanding physical change was observed.PCL2/1loses mass by0.5%in24wk,and molecular mass loses by61.7%with etches on cuttings sections.PCLA1/2loses mass by40.4in24wk,molecular mass loses by6.6%,and cracks and holes were observed as the main physical charac-ter.PLA lost mass by79.2%in24wk,molecular mass lost by15.1%and this material was totally degraded.
