Exploring the Influence of NC on the Crystallization of HTPE

A series of polymer blends of nitrocellulose (NC) and hydroxy terminated polyether (HTPE) in different proportions were prepared by a solution mixing method. The diffraction peak positions and peak intensities of the blends were analyzed by X-ray diffraction. The relative crystallinity of HTPE in the blends was analyzed by differential scanning calorimetry. The crystal morphology of the NC/HTPE blends was observed with a polarizing microscope. The results demonstrated that there is a certain degree of crystallinity in pure HTPE, while the crystallinity of NC/HTPE blends was gradually decreased as NC was added. In addition, when the mass fraction of NC in the blends was more than 40%, the crystallinity of the blends was hardly observed by these characterization methods, which demonstrated that the crystallinity of HTPE could be easily inhibited by NC.
