摘要： A method of making an attenuated-light-off hybrid catalyst, the method comprising combining a faster-light-off catalyst with an effective amount of a kinetics modifier compound of formula (A1), (B1), or (C1): R5-C≡C-R6 (A1), (R5)2C=C=C(R6)2 (B1), or (R5)(R7)C=C(R6)(R7) (C1) as defined herein under effective reaction conditions to give an attenuated hybrid catalyst that exhibits an attenuated light-off kinetics profile (relative to that of the faster-light-off catalyst); wherein the faster-light-off catalyst has been made by activating a hybrid precatalyst (i.e., an unactivated "coordination entity" or "ligand-metal complex") of structural formula (I): (Cp)(L)k(X)x (I) as defined herein; and related methods, compositions and uses.

摘要： A method of increasing bubble stability of a needful high molecular weight bimodal high-density polyethylene resin in need thereof, the method comprising subjecting the needful high molecular weight bimodal high-density polyethylene resin to a determined amount of oxygen tailoring of the resin so as to independently increase both the resin's melt storage modulus G' (at G'' = 3000 pascals) and complex viscosity ratio SH1000, and thereby make an oxygen-tailored high molecular weight bimodal high-density polyethylene resin having a targeted increase in bubble stability. The method uses a tailoring effective amount of molecular oxygen (O2) to achieve the desired oxygen tailoring. The method uses these advanced rheological properties from dynamic mechanical spectroscopy, but analyzes the data in a different way that is more sensitive to changes in resin composition and properties, and yet achieves a resin regime having a targeted increase in bubble stability.

摘要： A bimodal polyethylene-based composition that is useful for making under film extrusion conditions a film that beneficially has both decreased water vapor transmission rate and decreased haze. The composition comprises an improved design of the composition of the polyethylene blend of a higher molecular weight polyethylene polymer constituent and a lower molecular weight polyethylene polymer constituent and an effective amount of a nucleating agent. Additional embodiments include a method of making the bimodal polyethylene-based composition, a formulation comprising the bimodal polyethylene-based composition and at least one additive, a method of making a manufactured article from the bimodal polyethylene-based composition or formulation; the manufactured article made thereby, use of the bimodal polyethylene-based composition for protecting a moisture-sensitive material, and a sealed package made therefrom.A bimodal polyethylene-based composition that is useful for making under film extrusion conditions a film that beneficially has both decreased water vapor transmission rate and decreased haze.
