EPITAXIAL CRYSTALLIZATION OF LDPE ON IPP

Polymer Physics Laboratory, Changchun Institute of Applied Chemistry, Academia Sinica, Changchun 130022

Epitaxial crystallization of low-density polyethylene (LDPE) on highly oriented isotactic polypropylene (iPP) has been studied by electron microscopy.The results obtained by bright field (BF) electron microscopy and electron diffraction indicate that the LDPE can epitaxially grow on iPP substrate and form cross-hatched lamellae texture.The c axes of LDPE are ±50°apart from the c axes of iPP.The contact plane of two crystals is (010) of iPP and (100) of LDPE.
