PROPYLENE-BASED COPOLYMERS, A METHOD OF MAKING THE FIBERS AND ARTICLES MADE FROM THE FIBERS |
摘要 |
Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene- based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as having 13 C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress- induced crystallization by subjecting the fiber to tensile elongation during draw. |
