Hj. Kestenbach et al., EFFECT OF EPITAXIAL CRYSTALLIZATION ON ADHESIVE STRENGTH IN IMPACT-TOUGHENED ISOTACTIC POLYPROPYLENE, Polymer engineering and science, 38(3), 1998, pp. 478-484
The influence of the epitaxial crystallization of the polyethylene (PE
) content on the adhesive interface strength of impact-toughened isota
ctic polypropylene (iPP) has been investigated. The morphologies and c
rystal arrangements of four different matrix/rubber combinations were
observed by transmission electron microscopy (TEM) and were correlated
with the interface strengths measured by a peel test. It was found th
at the adhesion is best at interfaces, where an epitaxial morphology o
f the PE was observed.
