Abstract

While chemically similar, it has long been known that polyethylene (PE) and polypropylene (PP) are immiscible and suffer poor interfacial adhesion when processed as layered films or blends. In this paper we present an examination of the effect that processing conditions, such as extrusion residence time and post-extrusion take-up, have on the interfacial adhesion between PE and PP. We show that transient heat transfer analysis and rheological measurement can be used to determine processing conditions, which maximize adhesion between immiscible polymer pairs.
