Isothermal crystallization behavior of β-nucleated isotactic polypropylene with different melt structures
TL;DR: In this article, the authors investigated the impact of isothermal treatment on the polymorphic behavior and the isothermal crystallization kinetics of a β-iPP sample with different melt structures by differential scanning calorimetry.
Journal ArticleDOI
Differential scanning calorimetry (DSC) of semicrystalline polymers
TL;DR: This work addresses several unsolved problems regarding calorimetry of polymers, for example determination of baseline heat capacity, which is related to the problem of crystallinity determination by DSC, or the occurrence of multiple melting peaks.
Journal ArticleDOI
Confined crystallization of polymeric materials
TL;DR: In this paper, a change in nucleation mechanism, from heterogeneous nucleation to surface nucleation (or in extreme cases, homogeneous nucleations), was proposed, which reflected that nucleation is the rate determining step in the overall crystallization of ideally confined polymers.

Thermal and morphological characterization of nanocomposites prepared by in-situ polymerization of high-density polyethylene on carbon nanotubes
Mariselis Trujillo,María Luisa Arnal,Alejandro J. Müller,Estrella Laredo,Bredeau,Daniel Bonduel,Ph. Dubois +6 more
TL;DR: In this paper, the morphology, nucleation, and crystallization of polyethylene/carbon nanotubes nanocomposites were studied, and an excellent nucleating effect was found regardless of the CNT type.
Journal ArticleDOI
From Heterogeneous to Homogeneous Nucleation of Isotactic Poly(propylene) Confined to Nanoporous Alumina
TL;DR: The crystallization of highly isotactic polypropylene confined in self-ordered nanoporous alumina is studied by differential scanning calorimetry to enhance the understanding of nanocomposites containing semicrystalline polymers and reveal design criteria for polymeric nanofibers with tailored mechanical and optical properties.

Kinetics of Phase Change. I General Theory
TL;DR: In this paper, the theory of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment.
Journal ArticleDOI
Kinetics of Phase Change. II Transformation‐Time Relations for Random Distribution of Nuclei
TL;DR: In this article, a relation between the actual transformed volume V and a related extended volume V1 ex is derived upon statistical considerations, and a rough approximation to this relation is shown to lead, under the proper conditions, to the empirical formula of Austin and Rickett.
Journal ArticleDOI
Granulation, Phase Change, and Microstructure Kinetics of Phase Change. III
TL;DR: In this paper, a comprehensive description of the phenomena of phase change may be summarized in Phase Change, Grain Number and Microstructure Formulas or Diagrams, giving, respectively, the transformed volume, grain, and microstructure densities as a function of time, temperature, and other variables.

Physical Properties of Polymers
James E. Mark,K. L. Ngai,William W. Graessley,Leo Mandelkern,Edward T. Samulski,Jack L. Koenig,George D. Wignall +6 more
TL;DR: The third edition of this well known textbook as discussed by the authors discusses the diverse physical states and associated properties of polymeric materials and provides enough core material for a one semester survey course at the advanced undergraduate or graduate level.
