A polymer composition comprises a polyethylene polymer having a Melt Relaxation Ratio of 1.5 or greater and a salt of a branched alkyl phosphonic acid. A method for molding a thermoplastic polymer composition comprises the steps of (a) providing an apparatus comprising a die and a mold cavity; (b) providing the polymer composition described above; (c) heating the polymer composition to melt the polymer composition; (d) extruding the molten polymer composition through the die to form a parison; (e) capturing the parison in the mold cavity; (f) blowing a pressurized fluid into the parison to inflate the parison and conform it to the interior surface of the mold cavity; (g) allowing the molded article to cool so that the molded article retains its shape; and (h) removing the molded article from the mold cavity.

Provided are a liquid crystal polymer (LCP) film and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and a Kurtosis (Rku) of the first surface ranges from 3.0 to 60.0. With the Rku, the LCP film is able to improve the peel strength with a metal foil and ensure that a laminate comprising the same maintains the merit of low insertion loss.

An elastic film has a perforation formed by perforation holes that are elongated along a preferred expanding direction in the unexpanded state, wherein the ratio of the length of the perforation holes determined along the preferred expanding direction to a width of the perforation holes determined perpendicular thereto amounts to at least 3:2. The elongation at break along the preferred expanding direction is at least twice as high as the elongation at break determined perpendicular thereto along the width of the perforation holes.

The present disclosure provides device having a reaction vessel with one or more permeable membranes disposed therein that separate the reaction vessel into at least a first portion and a second portion. The one or more membranes permit first reactants from a first solution in the first portion or reactants from a second solution in the second portion to seep or percolate to a reaction zone proximate a surface of the one or more membranes. A reaction of the first and second reactants forms a two-dimensional polymer film material. A roller located inside of the reaction vessel draws the two-dimensional polymer film material reaction out of the reaction zone.
