Abstract

Fibers, tapes, monofilaments including copolymers of ethylene and α-olefins which exhibit improved tensile properties expressed as a balance between tenacity and elongation at break. The copolymers may be prepared by use of metallocene catalyst systems in particular by use of monocyclopenadienyl catalyst systems. The fibers, tapes, monofilaments of the invention are particularly suitable for end-use applications including artificial grass, woven and nonwoven fabrics, cordages, ropes, netting and flexible intermediate bulk containers.
