| 中文摘要 | in this work, we investigated the epitaxial crystallization and its determinant factor in the blends of high density polyethylene (hdpe) and a low crystallizable propylene-ethylene random copolymer (ppr) during injection molding. for ppr dominated blend (blended with 30 wt.% hdpe), epitaxial growth of hdpe on the ppr crystals can be achieved, as demonstrated by two-dimensional wide-angle x-ray diffraction and small-angle x-ray scattering measurements, though the crystallization of ppr was far behind that of hdpe component under quiescent conditions. in-situ shear infrared experiments indicated that ppr crystallized in advance mainly due to larger crystallization window and flow-induced crystallization acceleration. as for the blend with 70 wt.% hdpe, however, one could not observe epitaxy. shear-induced crystallization of hdpe hindered its epitaxial growth. once the formation of shish-kebab of hdpe was activated, the epitaxial growth would be suppressed to a large extent.
