  • Publication number: 20240075720
    Abstract: The present disclosure provides a multilayer film. The multilayer film includes at least two layers including a sealant layer and a second layer in contact with the sealant layer. The sealant layer contains (A) a first ethylene-based polymer having a density from 0.900 g/cc to 0.925 g/cc and a melt index from 0.5 g/10 min to 30 g/10 min; and (B) a polyethylene-polydimethylsiloxane block copolymer having a weight average molecular weight from 1,000 g/mol to 10,000 g/mol. The second layer contains a second ethylene-based polymer.

  • Patent number: 9732025
    Abstract: A process for conducting equilibrium-limited chemical reactions that produce water as a reaction product. Specifically, a process that uses a reactive chromatography unit (RCU) to improve the efficiency of equilibrium-limited reactions, such as a process for reacting glycol ether (GE) and carboxylic acid (CA) to form water and glycol ether ester (GEE). The process includes supplying GE and CA to the RCU, where one of either the CA or the GE is in a stoichiometric deficit relative to the other reactant. The reactant in the stoichiometric deficit reacts in the presence of the catalyst in the RCU to form a mixture of GEE and water. A raffinate is separated from the mixture using the separation media of the RCU contains at least the GEE. An extract separated from the mixture using the separation media of the RCU contains at least the water.

  • Patent number: 9630890
    Abstract: The present disclosure provides for a process for an equilibrium limited reaction using reactive chromatography unit (RCU) in which a first organic donor reactant (FODR) and a second organic acceptor reactant (SOAR) react to form a product mixture of a first acceptor product (FAP) and a second donor co-product (SDCP). The equilibrium-limited reaction does not produce water. The RCU has separation media to separate the product mixture into a raffinate and an extract. The FODR is in a stoichiometric deficit relative to the SOAR for the equilibrium limited reaction, so that the SOAR acts as the eluent for both the raffinate and the extract, and so as not to produce an azeotrope of FODR and the SDCP in the extract.

  • Publication number: 20160199754
    Abstract: A process for separating a divinyl hydrocarbon from a composition mixture stream containing at least a divinyl hydrocarbon and other components, the process including (a) passing a composition mixture feed stream containing at least (i) a divinyl hydrocarbon; and (ii) a monovinyl hydrocarbon, and/or (iii) a non-vinyl hydrocarbon through a process-scale chromatography unit; wherein the process scale chromatography unit includes a ligand exchange media comprising a metal adapted to form a ligand with an olefin functionality; wherein the metal of the ligand exchange media is loaded on an adsorbent; and wherein the divinyl hydrocarbon is adsorbed onto the ligand exchange media; (b) passing a weak first elution solvent through the unit to elute the monovinyl hydrocarbon and/or the non-vinyl hydrocarbon from the unit; (c) passing a strong second elution solvent through the unit to elute the divinyl hydrocarbon product stream from the unit; and (d) recovering the divinyl hydrocarbon product stream having been separa
