A propylene, .alpha.-olefin copolymer, where the .alpha.-olefin has 5 or more carbon atoms made with a metallocene catalyst system provides substantially higher cold flow resistance from when the propylene copolymer is made with an .alpha.-olefin having 4 or less carbon atoms. Other properties such as ultimate tensile strength and impact strength are substantially higher as well. Such polymers can be used to advantage in fibers, fabrics, and oriented films.
