Abstract: Embodiments of the present invention relate to multilayer films and articles. In one aspect, a multilayer film comprises at least one outer layer comprising at least 50 wt % of a polyethylene composition comprising the reaction product of ethylene and optionally, one or more alpha-olefin comonomers, wherein the polyethylene composition is characterized by the following properties: a. a melt index, I2, of from 0.3 to 3.0 g/10 min; b. a density of from 0.950 to 0.965 g/cm3; c. a melt flow ratio, I10/I2, of from 6.3 to 7.5; and d. a molecular weight distribution (MWD) of from 2.2 to 3.5, wherein the multilayer film has a thickness of at least 2 mils, wherein the multilayer film comprises at least 50% by weight polyethylene, wherein the multilayer film exhibits a surface haze of 13.5% or less when measured according to ASTM 1003-07, and wherein the multilayer film exhibit a water vapor transmission rate of 0.7 g-mil/100 in2/day or less when measured according to ASTM F1249-06 at a temperature of 38° C.

Abstract: Disclosed herein is a blown film comprising at least 50 wt. % of a polyethylene composition comprising the reaction product of ethylene and optionally, one or more alpha-olefin comonomers, wherein the polyethylene composition is characterized by the following properties: a melt index, I2, of from 0.1 to 2 g/10 min; a density of from 0.940 to 0.970 g/cm3; a melt flow ratio, I10/I2, of from 5.5 to 7.2; and a molecular weight distribution (Mw/Mn) of from 2.2 to 3.5.

Abstract: Prepare a branched alcohol-based sugar surfactant by: (a) providing an ether alcohol and a fully acetylated sugar where the ether alcohol has the structure of Structure (I); (b) coupling the ether alcohol with the acetylated sugar in the presence of a Lewis acid catalyst to form a branched glucoside acetate; and (c) deprotecting the glucoside acetate by removing the acetate moieties and replacing them with hydrogen atoms in the presence of a base to form a surfactant having the structure (II).

Abstract: This invention relates to a foam-forming composition and method of use thereof for enhanced oil recovery. Said foam-forming composition comprises an anionic sulfonate surfactant wherein the anionic sulfonate surfactant is biodegradable and has low aquatic toxicity. The method for recovering oil from a reservoir comprises the periodic injection of gas and said foam-forming composition into the reservoir and contacting the oil in the reservoir with the foam so as to assist in the recovery of oil from the reservoir.

Abstract: The present invention generally relates to a process that copolymerizes two or more polymerizable olefins, and to cataclyst comprising a metal-ligand complex (precatalyst). The present invention also generally relates to ligands useful for preparing the metal-ligand complex.
