    摘要： The invention relates to a process for the preparation of a hydrocarbylated metal organic compound, comprising a hydrocarbyl group, a spectator ligand and optionally a ligand, by contacting a metal-organic reagent with a spectator ligand in the presence of at least 2 equivalents of a hydrocarbylating agent. The invention further relates to a hydrocarbylated metal organic compound according to the following formula containing a spectator ligand S equal to (Ar—Z—)sY(—Z-DR′n)q, wherein Y represents the an anionic moiety of S bonded to M of the metal-organic compound, Z an optional bridging group between the Y moiety and the DR′n and/or Ar group, D an electron donating hetero atom chosen from group 15 or 16, R′ an optional substituent, Ar an electron-donating aryl group, n the number of R′ groups bonded to D, q and s integers with q+s≧1, wherein Y is an imine radical, or wherein the electron donating hetero atom containing group DR′—n is a ketimide, phosphinimide, guanidine, or iminoimidazoline, or a combination thereof.

    摘要： 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 13C 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) 13C 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, Six, greater than about −1.20, (iv) a DSC curve with a Tme that remains essentially the same and a Tmax 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.
