The present invention relates to multilayer films. In one aspect, a multilayer film comprises a first polyethylene composition having a density of at least 0.965 g/cmand as further described herein and a second polyethylene composition having a density of 0.924 g/cmto 0.936 g/cmand as further described herein, wherein the multilayer film comprises 40 weight percent or less of the first polyethylene composition based on the total weight of the multilayer film.

Multilayer films and articles comprising the same

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.

Multilayer films and laminates containing slip agents

A method of making a hollow fiber carbon molecular sieve is comprised of heating a hollow polymer fiber to a carbonization temperature in an atmosphere that is non-oxidizing to form a hollow fiber carbon molecular sieve, wherein during at least a portion of the heating a tensile force is applied to the hollow polymer fiber. The method may improve the separation of gases similar in size such a propylene from propane.

Method to make carbon molecular sieve hollow fiber membranes

The present disclosure provides a composition containing a polymeric blend. The polymeric blend contains (A) from 50 wt % to 90 wt % of a first ethylene-based polymer having a density from 0.895 g/cc to 0.905 g/cc; and a melt index from 0.1 g/10 min to 50 g/10 min; (B) from 8 wt % to 48 wt % of a second ethylene-based polymer having a density from 0.935 g/cc to 0.967 g/cc; and a melt index from 0.1 g/10 min to 180 g/10 min; and from 0.01 wt % to 2.0 wt % of a slip agent, based on the total weight of the polymeric blend. The polymeric blend has (i) an overall density from 0.900 g/cc to 0.925 g/cc; and (ii) a coefficient of friction (COF) after aging for 1 week at 60&#xb0; C. from 0.001 to 0.400. The present disclosure also provides a multilayer film with a first layer containing the composition.

Low coefficient of friction ethylene-based compositions

An asymmetric hollow fiber (CMS) carbon molecular sieve is made by providing a dope solution comprised of a polvimide and a solvent, at a temperature greater than 250&#xb0; C. that is less than the storage modulus at a temperature of 250&#xb0; C., but no more than ten times less as measured using dynamic mechanical thermal analysis from 250&#xb0; C. to a temperature where the polyimide carbonizes. The polvimide is shaped into a hollow polvimide fiber, the solvent removed and the polyimide hollow fiber is heated to pyroiyze the polvimide and form the asymmetric hollow carbon molecular sieve. The asymmetric hollow fiber carbon molecular sieve has a wall that is defined by an inner surface and outer surface of said fiber and the wall has an inner porous support region extending from the inner surface to an outer raicroporous separation region that extends from the inner porous support region to the outer surface. Surprisingly, when the polyimide has the particular storage modulus characteristics, the method allows for the hollow fiber CMS to be made without any pre-treatmenis or additives to inhibit stractural collapse of the inner microporous region.
