Beschreibung
Zusammenfassung:	There is described a process utilizing Ziegler-Natta catalysts for producing ethylene/olefin interpolymers which, for a given melt index and density, have a reduced melting peak temperature (Tm). The process involves contacting ethylene and at least one other olefin under polymerization conditions with a Ziegler-Natta catalyst and at least one modifier comprising at least one element from Group 15 and/or Group 16 in amounts sufficient to reduce the melting peak temperature of the ethylene/olefin interpolymer. Also described herein are novel ethylene/olefin interpolymers resulting from the process.
