Abstract:
Propylene homopolymers having a melt flow index in the range from 3.0 dg/min to 8.0 dg/min can be particularly suited for high-tenacity fibers and yarns and nonwovens. The propylene homopolymers can be produced by a process that can include polymerizing propylene in presence of a Ziegler-Natta polymerization catalyst, an aluminum alkyl, hydrogen and an optional external donor.
