A method for producing particles, the method including: depolymerizing a resin to obtain a depolymerized product; contacting the depolymerized product obtained in the depolymerizing with a first compressive fluid to obtain a melted product; and jetting the melted product obtained in the contacting to granulate the particles.

The present invention relates to polyvinyl chloride aggregate particles, in which a particle diameter D50 at a cumulative volume percentage of 50 vol % in a volume particle size distribution is 0.5 μm or more and 5.0 μm or less, and a particle diameter D90 at a cumulative volume percentage of 90 vol % in the volume particle size distribution is 8.0 μm or less, and a Na concentration in the polyvinyl chloride aggregate particles is 90 ppm or less. The present invention relates to a composition for a metal can coating material, a composition for a marking film and a method for producing the same, and a coating film that contain the polyvinyl chloride aggregate particles. This provides polyvinyl chloride aggregate particles capable of imparting high transparency and retort resistance to a coating film of a metal can, and/or capable of imparting high transparency and water resistance to a marking film.

A polyvinyl alcohol film is provided, which is highly transparent, and excellent in antistatic property and cold-water solubility. The polyvinyl alcohol film contains: (A) a polyvinyl alcohol resin; and (B) an ester of a C2 to C4 fatty acid (b1) and a polyhydric alcohol (b2); wherein the ester (B) is present in an amount of 1 to 4,000 ppm.

The present invention relates to processes for making compatibilized high aspect ratio barrier additives and polymer compositions that comprise compatibilized high aspect ratio barrier additives. The invention also relates to compositions produced by these processes, and articles formed from polymer compositions of this invention. The barrier additives provide passive barriers to gas molecules such as oxygen and carbon dioxide minimizing transit of such molecules through sidewalls of polymer articles containing the barrier additives.

The chemical product packaging film of the present invention is a chemical product packaging film comprising a polyvinyl alcohol resin, a plasticizer, and water-soluble starch, the water-soluble starch having solubility in which the water-soluble starch dissolves when stirred in water having a concentration of the starch of 10% by mass at a temperature of 50 C. for 30 minutes, a content of the water-soluble starch being 4% by mass or less.

Disclosed are a separator for secondary batteries with enhanced stability and a method of manufacturing the separator. The separator can prevent self-discharge which may occur when a porous non-woven fabric material is used for a separator; can perform a shutdown function at a high temperature of 200 C. or less; and can avoid even under harsh conditions of high temperatures, deterioration in stability caused by internal short-circuit of positive and negative electrodes. In particular, the separator for secondary batteries of the present invention includes a porous non-woven fabric material impregnated with a baroplastic polymer powder and pores of the porous non-woven fabric material are filled with the baroplastic polymer powder by pressing an assembly of the secondary battery.
