Effect of Mechanical Compression and Hydrostatic Pressure on the Molecular Mobility of Poly(lactic acid)

Effect of Mechanical Compression and Hydrostatic Pressure on the Molecular Mobility of Poly(lactic acid)

Summary The molecular mobility of an organic glass (PLA with 4.3% of D‐lactic acid content) was investigated by calculating the size of the Cooperative Rearranging Regions (CRR) at its glass transition. The samples were exposed to different external constraints – namely a large deformation by mechan...

Zusammenfassung:Summary The molecular mobility of an organic glass (PLA with 4.3% of D‐lactic acid content) was investigated by calculating the size of the Cooperative Rearranging Regions (CRR) at its glass transition. The samples were exposed to different external constraints – namely a large deformation by mechanical compression at T
