The amount of immobilized polymer in PMMA SiO2 nanocomposites determined from calorimetric data
TL;DR: In this paper, it was shown that the interaction between the SiO2 nanoparticles and the PMMA is so strong that no devitrification occurs before degradation of the polymer.

Melting process and the equilibrium melting temperature of polychlorotrifluoroethylene
John D. Hoffman,James J. Weeks +1 more
TL;DR: In this paper, a new method of estimating the equilibrium melting temperature, Tm, of a polymer is described, and applied to polychlorotrifluoroethylene (PCTFE), where the data fit a straight line of positive slope on a Ti (obs) versus Tx plot, Tx being the abscissa.

From the melt via mesomorphic and granular crystalline layers to lamellar crystallites: A major route followed in polymer crystallization?
TL;DR: In this article, a novel concept for understanding the crystallization of polymers from the melt is developed based on broad and detailed evidence from a large variety of experiments on several polymer systems carried out by other authors and ourselves.

The melting behaviour of heat crystallized poly(ethylene terephthalate)
P.J. Holdsworth,A. Turner-Jones +1 more
TL;DR: In this article, it was shown that double melting peaks in the differential scanning calorimetry (dsc ) and x-ray techniques are due to a recrystallization and melting process taking place while the material is being scanned and not a direct reflection of the state of the material at room temperature prior to the scan.
