✦ Synopsis

The recrystallization behavior of high-density polyethylene (HDPE) on the highly oriented isotactic polypropylene (iPP) substrates at temperatures below the melting temperature of HDPE has been investigated by means of transmission electron microscopy. The results obtained by the bright-field observation and the electron diffraction show that upon annealing the HDPE-quenched films on the oriented iPP substrates at temperatures below 125ЊC, only a small amount of HDPE recrystallizes on the iPP substrate with [001] HDPE //[001] iPP , while annealing the HDPE-quenched films at temperatures above 125ЊC, all of the HDPE crystallites recrystallize epitaxially on the iPP substrate with [001] HDPE //[101] iPP .

Although under normal conditions only the crystallization behavior of PE on oriented iPP substrates can be studied due to the higher melting point of iPP, the faster crystallization rate of a molten, oriented HDPE film compared to a nonoriented iPP layer was used to study the crystallization of iPP
