Effects of crystallization condition of poly (butylene succinate) component on the crystallization of poly (ethylene oxide) component in their miscible blends

He, Yong, Zhu, Bo, Kai, Weihua, Inoue, Yoshio·2004·Macromolecules

Abstract

The crystallization behavior of the poly(ethylene oxide) (PEO) component in poly(butylene succinate) (PBS)/PEO blends with the middle PEO content was investigated as a function of isothermal crystallization temperature of the PBS component ( T IC,PBS ) using differential scanning calorimetry (DSC). It is found that the crystallization behavior of the PEO component in these blends is significantly affected by T IC,PBS . Small-angle X-ray diffraction (SAXS) measurements were performed to explore the origin of the T IC,PBS dependence of crystallization of PEO component. On the basis of the SAXS measurements and the results of our previous work [ Macromolecules 2004, 37, 3337−3345], it is suggested that T IC,PBS controls the location distribution of the PEO component in the blends after the crystallization of the PBS component and thus significantly affects the crystallization behavior of PEO.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
