In order to separate the two thermal events, temperature-modulated DSC (TMDSC) was used.
Interaction between the functional groups of PLA and PPC provides partial miscibility of the two polymers, as revealed by TMDSC and DMA analysis.

Temperature modulated differential scanning calorimetry (TMDSC) and dynamic mechanical analysis (DMA) were used to investigate the molecular dynamics of PLA/Cloisite 15A nanocomposites, during annealing, at different times and temperatures.
Since the ageing history has a strong influence on the form of the C" signal [38], only non-aged samples are characterized with TMDSC. For both DSC and TMDSC, the uncertainties on temperature are [+ or -] 0.5[degrees]C and on the heat capacity step [+ or -] 0.04 J [g.sup.-1] [K.sup.-1].
Temperature modulated DSC (TMDSC) was used for monitoring the vulcanization reaction of hydroxyl-terminated PDMS/ organoclay nanocomposites, in comparison with pure PDMS systems.
Specific heat capacities of the glass ([C.sub.pglass]) and the liquid-like state ([C.sub.pliquid]) at constant pressure, and [DELTA][C.sub.p] values were determined from TMDSC performed on a Mettler Toledo DSC 1.
Compared to other approaches, the main advantage is that the resulting fluctuation of the dynamic glass transition temperature can be obtained empirically by means of TMDSC. Indeed, by applying the fluctuation-dissipation theorem and modeling the out-of-phase component C" as a Gaussian curve (supposing temperature variable and frequency constant), [delta]T corresponds to the standard deviation of this Gaussian curve [52] and [T.sub.[alpha]] is its maximum.

Hourston and Song [20] recommended a temperature modulated differential scanning calorimetry (TMDSC) method for such quantitative measurements.
The crystallized samples were characterized by using temperature-modulated differential scanning calorimeter (TMDSC, TA2920, TA Instruments) at the heating rate of 5[degrees]C [min.sup.-1], to determine the melting temperature ([T.sub.m]) and heat of fusion ([DELTA]H) of PP-MA and PPCNs.
Two different molecular weights were studied by Temperature Modulated DSC (TMDSC) over a broad range of annealing times and temperatures.
