Crystallization Kinetics in Non-isothermal Process of Polypropylene II, Shuhei Yasuda, Tsuguhisa Miyamoto, Ken Taguchi, Akihiko Toda, 2023/06/21, Without Invitation, Japanese, The Japan Society of Polymer Processing, Chiba, Crystallization kinetics during molding process requires evaluation under a non-constant high-speed cooling of several tens of ℃/s. In this study, crystallization behavior under high-speed cooling conditions was evaluated by using fast scanning chip calorimetry. In addition, we proposed the equations predicting the absolute crystallinity attained under general conditions including non-isothermal processes. The numerical results of the model well reproduced the experimental results, indicating the applicability of the model.

The WAXS results showed that γ form melts at lower temperatures than α but the equilibrium melting temperatures are almost the same for each form. The SAXS analysis tells that lamellar thickness of each form are almost the same, although the long period of α lamellar layer is larger. We discuss the relation between the melting behavior and the polymorphic growth mechanism of lamellar crystal structure.

We found that the equilibrium melting temperatures of γ and &alpha crystals are almost the same through the Hoffman-Weeks plots of each phase, although the melting behavior of each polymorph is different. We discuss the correlation between the melting behavior and the lamellar crystal structure of each polymorph.
  12. Polymorphic transition kinetics of triacylglyceride crystallization accompanied by melting, Ken TAGUCHI, Akihiko Toda, Hironori Hondoh, Satoru Ueno, Kiyotaka Sato, JCCG-49, 2020/11/11, Without Invitation, Japanese, the Japanese Association for Crystal Growth, On-line, For the isothermal melt growth of the 1:1 triacylglycerol mixture of POP and OPP, we have found that needle-like metastable alpha form crystals grow at first and after that beta’ spherulite crystals grow slowly at later stage with accompanying the melting of the alpha form crystals near the melting temperature of alpha form. This polymorphic transition kinetics indicates that the alpha form crystals growing at first is that of pure OPP and the beta’ spherulite at later stage is of molecular compound of POP-OPP.

We found that the equilibrium melting temperatures of γ and &alpha crystals are almost the same using the Hoffman-Weeks plots of each phase, i.e. the dependence of melting temperatures on the growth temperatures. We discuss the growth mechanism and melting behavior of each phase in terms of the lamellar crystal structure.

We found that the fraction of γ phase gradually increases during the isothermal crystallization and also the fraction is relatively high in the inner part of the spherulite. We discuss the time-development and spatial distributions of the γ phase in the spherulites in terms of the growth mechanism of γ and α crystals.

It was observed that morphology changes and the growth rate decreases with decreasing film thickness regardless of the thin film forming conditions and growth temperature as observed for other polymer ultrathin films. The crystal growth mechanism in ultrathin films are discussed in terms of morphology, kinetics and polymorphism.

Two types of morphology are observed in ultrathin films of the (P-E)RCP, the lozenge and the curved cross-hatching morphology, which consists of S-shape needle-like crystals. The electron diffraction and microbeam X-ray diffraction revealed that the lozenge crystal consists of γ-phase needle-like crystals and the cross-hatching structure S-shape curved α edge-on crystals. We discuss the origin of S-shaped morphology in terms of chain tilting in the the edge-on lamellar crystals.

Molecular weight dependence of polymer crystal growth in ultrathin films can reveal the chain dynamics in ultrathin films on the substrate. We discuss some features of the polymer crystallization from ultrathin films and the effectiveness for the study of polymer crystallization.

The γ-phase of the polypropylene crystal appears at growth temperatures from ca. 70 ℃ to 120 ℃ in the bulk sample and has a maximum fraction of almost 90 % around 107 ℃. We report the growth temperature and hence γ-phase fraction dependence of lamellar morphology and discuss the relationship between SAXD profile and lamellar stacking structure observed by AFM and TEM in the copolymer samples.

  24. Crystal growth of isotactic polypropylene in ultrathin films, Youhei NODA, Akihiko TODA, Ken TAGUCHI, 66th SPSJ Annual Meeting, 2017/05/31, Without Invitation, Japanese, The Society of Polymer Science of Japan, Chiba, Japan, Polymer crystallization shows interesting growth behaviors when crystallized in ultrathin films that have thickness equivalent to the radius of gyration of polymer molecules. Some articles about crystallization in ultrathin films tell the changes in morphology and growth rate reduction with film thickness. In this study, we investigated the crystallization of isotactic polypropylene in ultrathin films by a differential interference contrast optical microscope and an atomic force microscope. As a result, the decrease in growth rate and changes in morphology have appeared for isotactic polypropylene in a similar way as other polymers that have been previously studied in ultrathin films.

In thin films crystallization, two types of crystal morphology are observed; elongated lozenge shape and curved crosshatch structure. We report the temperature dependence of these two types of morphology and discuss the relevance to the crystal polymorphism and in particular to the γ-phase fraction in the bulk samples.
