The present invention provides: a resin pellet composition excellent in terms of low-classification property, kneadability with liquid ingredients, and transportability; a method for producing the resin pellet composition; and a method for producing a microporous polyolefin film from the resin pellet composition. The resin pellet composition comprises first pellets, which comprise a polyolefin, and 0.1-99.0 mass % liquid component. The first pellets are porous objects, some of which contain some of the liquid component infiltrated thereinto. In another embodiment, the resin pellet composition includes second pellets, which include a polyolefin. The second pellets are non-porous objects each comprising a portion made of a resin comprising the polyolefin and a portion made of a liquid component. The mass of the liquid component present on the outer surfaces of the second pellets is 20 mass % or less with respect to the total mass of the second pellets.

A method of treating a polycarbonate glass surface, such as a bisphenol A polycarbonate, whereby the glass surface is immersed in a liquid phase polar aprotic solvent, such as dichloromethane, and exposed to a vapor phase polar aprotic solvent, such as acetone thus obtaining a textured glass surface with a hierarchical patterned nanoporous structure wherein the textured glass surface has a higher surface hydrophobicity and a marginally reduced optical light transmittance relative to the polycarbonate glass surface prior to the immersion, the exposure, or both.

Disclosed herein is a nano membrane. The nano membrane includes an insulating layer having a thickness corresponding to a diameter of each of metal nanowires and configured to contain the metal nanowires therein, and the metal nanowires arranged to cross and having portions of side surfaces which protrude from one surface of the insulating layer.

In a method for the chemical smoothing of components composed of plastic, said components are immersed at atmospheric pressure in a pre-temperature- controlled process liquid composed of glycol.

A method is provided for treating a surface of a molded part produced in a 3D printing method. In the method, the molded part is introduced into a pressure-tight container, negative pressure, preferably a vacuum to a large extent, is generated in the container after introducing the molded part, a solvent is heated up to a specified solvent temperature, and the heated solvent is introduced from a solvent container into the container under negative pressure. In such a method, the temperature of the molded part is lower than the solvent temperature, and the solvent is evaporated or is introduced as a vapor upon being introduced, the solvent vapor condensing on the surface of the molded part. Also provided is a device for carrying out the method.

A method is described in which a part is placed within a chamber. Vaporized solvent is provided within the chamber such that the solvent condenses onto and treats the part. A vacuum is then applied to the chamber to extract the solvent and stop the treatment. The vacuum is controlled such that a pressure within the chamber over time has a predefined profile to prevent defects in the part from occurring due to the extraction of solvent from the part.

The present disclosure relates to the formation of terephthalate esters. The present invention also relates to the depolymerization of polyethylene terephthalate (PET) or poly(ethylene glycol-co-1,4-cyclohexanedimethanol terephthalate) and the recovery of terephthalate esters.
