  Fibers comprising a propylene homopolymer or a copolymer of propylene and at least one of ethylene and one or more unsaturated comonomers exhibit desirable properties. The homopolymers 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. The copolymers are characterized as (A) comprising at least about 60 weight percent (wt %) of units derived from propylene, and (B) having at least one of the following properties: (i) 13 C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity, (ii) a B-value greater than about 1.4 when the comonomer content of the copolymer is at least about 3 wt %, (iii) a skewness index, S ix , greater than about −1.20, (iv) a DSC curve with a T me that remains essentially the same and a T max that decreases as the amount of comonomer in the copolymer is increased, and (v) an X-ray diffraction pattern that reports more gamma-form crystals than a comparable copolymer prepared with a Ziegler-Natta (Z-N) catalyst.

  由丙烯单体或丙烯与乙烯和一种或多种不饱和共聚单体共聚而成的纤维具有理想的性能。单体共聚物的特点是具有13C NMR峰，对应于大约14.6和15.7 ppm处的区位误差，峰强度大致相等。共聚物的特点是（A）至少包含约60重量％（wt％）的来自丙烯的单元，以及（B）具有以下至少一种性质：（i）13C NMR峰对应于大约14.6和15.7 ppm处的区位误差，峰强度大致相等，（ii）当共聚物的共聚单体含量至少为约3 wt％时，B值大于约1.4，（iii）偏斜度指数Six小于约-1.20，（iv）具有Tmethat保持基本相同和Tmax随共聚物中共聚单体量的增加而降低的DSC曲线，以及（v）比使用Ziegler-Natta（Z-N）催化剂制备的类似共聚物更多的γ形晶体的X射线衍射图案。

  New compositions, titanium-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with titanium metal centers have high performance characteristics, including high styrene incorporation into ethylene/styrene copolymers.
