The extent to which plasticization of ultrahigh molecular weight (UHMWPE) can modify the micro- as well as macro-structural properties of HDPE/UHMWPE blends as well as

Also, the melting temperature of the films decreased by increasing the content of plasticizers. Melting temperatures of SOR containing films were lower than PEG containing the

Does plasticizer content affect melt viscosity and thermal properties of PHB?
The effect of plasticizer content on the melt viscosity, thermal properties (DSC), spectral characteristics (ATR-FTIR), tensile properties and water permeability was investigated in order to improve the processability and properties of PHB. . DSC results of PHB/plasticizer blends Sample code T c ( o C) T m ( o C) H f (J/g) X c (%)
Do plasticizers affect melting temperature?
Furthermore, presence of plasticizers can also alter different characteristics within the crystalline regions, as crystallite size and, accordingly, the melting temperature (Tm). In fact, a depression of Tm has been described in previous investigations [8, 9].
Can plasticizers reduce material degradation over time?
The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
Does plasticizer affect the crystallization rate of PLA?
A content of 10 wt.% in TOTM has been chosen for this study, both without and with MCM-41 silica, based on the results attained in our previous investigation and in order to reach a good compromise between the amount of plasticizer and the effect on the crystallization rate of PLA (and on the actual crystallization window).
How does molecular weight affect plasticization efficiency?
The molecular weight (Mw), number hydroxyl group units, shape of molecules of plasticizers affects the plasticization efficiency . It was reported that in the literature low Mw plasticizers were more efficient than the high one [40, 41].
How does plasticizer affect permeability of biodegradable films?
The addition of PEG and SOR to the PVA/CA film affected the permeability differently. The addition of PEG decreased WVP of PLAST-0 the film by 14%, while the addition of SOR increased by 90% in the same amount. The increasing of WVP of biodegradable films with the addition of plasticizer has been reported in different studies [22, 35, 37].
