The transesterification reaction scissors the long chain of PC to short segments, decreasing the Tgs of the blend system.
Blending with PEG significantly decreased the Tg, decreased the modulus and increased the fracture strain of PLA.
The dye was found to decrease the Tg of some polymers (plasticization) while increasing the Tg of others (antiplasticization).
The addition of poly ethylene glycol) decreased the Tg or increased the amorphous property of the polylactide drastically.
Blending poly ethylene glycol) (PEG) with poly(lactide) (PLA) decreases the Tg and improves the mechanical properties.
Saturation of the main-chain double bonds of poly(CbzNB) increases the thermal stability of the polymer but decreases the Tg of polymer.
The dissolution of CO2 in PC dramatically reduces its glass transition temperature in proportion to the amount of CO2 absorbed: incorporation of 20.4% CO2 in PC decreased the Tg from 147 °C down to −7.5 °C.
The C-II-a peptide restored normal lipolysis in plasma from APOC2-deficient human patients and dramatically decreased the TG levels in Apoe −/− mice (Amar et al., 2015).
In parallel, leptin treatment significantly decreased the triglyceride (TG) levels both in the serum and liver (Figure 5D).
