Abstract: The embodiments described herein pertain to constrained geometry catalyst (CGC)-type titanium catalyst compounds with an amido moiety that features asymmetric substituents that give rise to diastereomerism in new catalysts. Catalyst compounds embodying the present technological advancement are excellent catalysts for variety of transformations including homopolymers of propylene (P), ethylene (E), ethylene-propylene (EP)-copolymers and ethylene-octene (EO) copolymers.

Abstract: This invention relates to a homogeneous process to produce propylene polymers using transition metal complexes of a dianionic, tridentate ligand that features a central neutral heterocyclic Lewis base and two phenolate donors, where the tridentate ligand coordinates to the metal center to form two eight-membered rings. Preferably the bis(phenolate) complexes are represented by Formula (I): where M, L, X, m, n, E, E?, Q, R1, R2, R3, R4, R1?, R2?, R3?, R4?, A1, A1?, and are as defined herein, where A1QA1? are part of a heterocyclic Lewis base containing 4 to 40 non-hydrogen atoms that links A2 to A2? via a 3-atom bridge with Q being the central atom of the 3-atom bridge.

Abstract: This invention relates to a polyethylene composition, and films therefrom, comprising at least 65 wt % ethylene derived units and from 0.1 to 35 wt % of C3-C12 olefin comonomer derived units, where the polyethylene composition has: a) an RCI,m of less than 85 kg/mol; b) a Tw1?Tw2 value of from ?15 to ?40° C.; and c) an Mw1/Mw2 value of less than 1.5 where the film has a) a heat seal initiation temperature of X ° C. or less at 5 N of force, where X=0.0015×Y(psi)+62.6 (where Y is the average 1% Secant modulus ((MD+TD)/2)) of the film; b) a dart drop impact of 300 g/mil or more; c) an MD Elmendorf tear of 230 g or more; and d) average 1% Secant modulus ((MD+TD)/2) of 20,000 psi or more.
