Abstract: A molded article of polyolefin-based resin expanded beads having excellent appearance and further suppressed color unevenness is provided. Polyolefin-based resin expanded beads obtained by expanding polyolefin-based resin particles including one or two or more metal borates selected from zinc borate and magnesium borate, wherein the particles of the metal borate has an arithmetic average particle diameter based on the number of 1 ?m or more, and a number rate of the particles of the metal borate having a particle diameter of 5 ?m or more is 20% or less.

Abstract: A crosslinked olefin-based thermoplastic elastomer expanded bead including a base polymer having an olefin-based thermoplastic elastomer and a brominated bisphenol-based flame retardant having a chemical structure represented by formula (1). A difference TmTPO-TFR is ?5° C. to 40° C., where TmTPO is a melting point of the olefin-based thermoplastic elastomer and TFR is the lower of a glass transition temperature TgFR and a melting point TmFR of the brominated bisphenol-based flame retardant. A xylene insoluble content is 5 mass % to 80 mass %.

Abstract: A process for producing a cellulose acetate molding material which comprises dissolving cellulose diacetate in a mixed solvent of acetone and water to prepare a dope and then spinning or film forming the dope, wherein at least one compound selected from the group consisting of water-soluble salts and bases is added to the water to be used in preparation of the dope.

Abstract: A method for manufacturing cigarette filters which have a well-stabilized shape in which acetate fibrous tows impregnated with carboxylic acid ester of polyol are formed into a predetermined shape, uniformly impregnated with water, and irradiated with microwave energy. Water is used during the application of microwave energy to enhance the absorption of microwave energy and hence heating of the filter. This causes the carboxylic acid ester of polyol to very rapidly disperse causing it to permeate into the acetate fiber to rapidly complete the stabilization and solidification of the filter.

Abstract: An oil-adsorbing composition useful for removing oil from oil-contaminated water comprises a granulated mixture of 5-80 weight % of an inorganic filler capable of adsorbing oil and 95-20 weight % of a cross-linked polymer. The composition is melt-kneaded by mixing and crushing the ingredients while cross-linking the polymer.

Abstract: A translucent polypropylene film containing no .beta.-type crystallization nucleating agent which has, on at least one side, a surface layer composed of a two- or three-dimensional network structure, in which at least 1,000 network elements constituting the said network structure are present per cm.sup.2 of the film surface. The said film is obtained in such a manner that an unstretched polypropylene film having, on at least one side, a surface layer having a K value, which represents the amount of .beta.-type crystals present at a portion from the surface to a thickness of 10% in the thick-wall direction, of at least 0.1 is biaxially stretched under such conditions that the stretching temperature at the stretch initiation point is in the range of 145.degree. to 176.degree. C. and the stretch ratio in one direction is less than 8 times.
