g] of the PPC phase increases, as revealed by TMDSC.
The increase of spherulite growth rate of PLA has been rationalized taking into account the results of TMDSC and DMA analysis, which probed a progressive decrease of the glass transition of the PLA-rich phase with the nominal PPC content in the blends.
To investigate the influence of the plasticizing molecules on the molecular mobility of PLA, standard DSC and TMDSC analysis are performed on each material.
The molecular mobility of plasticized non-aged samples is investigated with TMDSC using the CRR concept.
Calculation of the Weight Fraction of the Interface Using TMDSC Results
The weight fraction of the interface was calculated using TMDSC results, as suggested by Hourston and Song [20].
The same equation can be used also for miscible or partially miscible systems if the two constituent polymers are not mixed before the TMDSC analysis.
Therefore, in brief, the procedure for the calculation of the weight fractions in the interface was the following: By TMDSC analysis the [DELTA][C.
With TMDSC and an independent rapid heating rate technique for determining melting points without recrystallization contributions (14, 23), we have approximately confirmed the model of Zhou et al.
One must remember that standard DSC cannot usually resolve the two highest transitions for a variety of reasons explored more directly in the TMDSC characterization below.
Also, contrary to our previous claim where part of the secondary melting phenomenon was masked by recrystallization because of the low heating rates of TMDSC (14), Marand et al.
