Isothermal crystallization of isotactic polypropylene blended with low molecular weight atactic polypropylene. Part I. Thermal properties and morphology development

TL;DR: Residual stress in semicrystalline plastics drives the release of amorphous polymer micropollutants into water through stress-induced phase separation, with highly compressed regions of plastic bottles being a primary source of these pollutants.

TL;DR: In this article, the structure, morphology, and isothermal crystallization behaviors of polypropylene (PP) prepared with heterogeneous Ziegler-Natta catalyst at high tempera- ture (100 � C) were investigated with differential scanning calorimetry, wide-angle X-ray diffraction, temperature- rising elution fractionation, gel permeation chromatogra- phy, and 13 C NMR.

TL;DR: Department of Biochemistry and Microbiology Institute of Biosciences UNESP, Rio-Claro, Sao Paulo presents a new probabilistic method called “supervised cell reprograming” to characterize the response of the immune system to EMT.

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.

TL;DR: The crystal structure of isotactic polypropylene and its chemical-physical properties are described in this article, where the polymer crystallizes in the Cc space group with the following constants of the unit cell.

TL;DR: A survey of spherulites formed by the isothermal crystallization of polypropylene from the melt in the temperature range 110°−148°C is given in this paper. But their structural morphology, optical properties, melting behavior, and growth rates have not been examined.

TL;DR: In this paper, a systematic study of impurity segregation in spherulitic crystallization is described, in which the role of impurities is fulfilled by stereoirregular molecules or by molecules of low molecular weight.
