The accelerated degradation of the blend is attributable to auto-catalytic behaviour: faster degrading PLCL-PEG breaks down, accumulating catalytic oligomers formed by hydrolysis, which then catalyse degradation of PLLA and further degradation of PLCL-PEG.
“This can be attributed to auto-catalytic behaviour [47, 48] - as the faster degrading PLCL-PEG breaks down, there is an accumulation of catalytic oligomers formed by hydrolysis, which then catalyse degradation of PLLA as well as further degradation of PLCL-PEG.”

For amorphous PLA, there is a period in the earlier stages of degradation during which Young's modulus and tensile strength remain constant before decreasing.
“However, many authors observed that it exists a period, especially for amorphous PLA, in the earlier stages of degradation, for which Young's modulus and tensile strength remain constant before decreasing (Tsuji, 2002; Karjalainen et al., 1996; Leroy et al., 2013).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
