The sheet may be formed into a vessel having a multilayered wall structure by hot molding.

Abstract: Disclosed is a process for preparing a polyarylene sulfide, which involves polycondensing a dihalogenated aromatic compound with a source of sulfur in an organic polar solvent while dehydrating at pressure under which polycondensation is performed. This process avoids dehydration operation of the raw materials, particularly the source of sulfur, prior to polycondensation, thereby resulting in the production of the polyarylene sulfide having a high molecular weight.

The diamond which is synthesized is separated from the substrate. The use of the interrupting layer, composed of the inorganic fine powders, allows ready separation of the diamond from the substrate and the diamond separated is suitable for diaphragms for speakers, heat conductive plates, cutting tools, semiconductors, etc. by appropriately choosing shapes of the substrate. Further, the resulting diamond film can be pulverized, thereby yielding diamond powders which are useful for abrasive tools, cutting tools, etc.

Abstract: A process for washing a powdery and/or granular resin involves bringing the powdery and/or granular resin into contact with a washing liquid in a counterflow fashion in a tubular body with a plurality of static mixing elements disposed continuously in series, thereby removing impurities adhering to the powdery and/or granular resin and producing the powdery and/or granular resin with a less content of impurities. A washing device for use with the washing process contains a tubular body in which the static mixing elements are disposed continuously in series, and this construction is simpler than conventional ones and does not require a stirring power and mechanism to remove the impurities from the powdery and/or granular resin.
