Abstract
AbstractEpitaxial crystallization of trans‐1,4‐polybutadiene (PBD) on highly oriented isotactic poly(propylene) (iPP) has been investigated at different crystallization temperatures and rates. From electron microscopy and electron diffraction, it is confirmed that epitactic growth of the low‐temperature modification (monoclinic) with microcrystals of PBD on the iPP films takes place with their chain directions about ±50° apart. No epitaxial relationship occurs between the high‐temperature modification (hexagonal) of PBD and the iPP substrate. Thermal analyses of PBD‐PP layered films indicate that the epitaxy has an important effect on the formation of the high‐temperature modification of PBD.
