A foaming resin composition of the present invention contains an aromatic vinyl-based resin and zinc oxide, wherein the size ratio (B/A), in which peak A is a 370 nm to 390 nm region and peak B is a 450 nm to 600 nm region, of zinc oxide is approximately 0.01 to approximately 1 when photoluminescence is measured, and the BET surface area thereof is approximately 1 m.sup.2/g to approximately 10 m.sup.2/g.

The present disclosure relates to a polymer foam and a preparation method thereof. The polymer foam is obtained by physically foaming a thermoplastic elastomer or a polyolefin material, and has an apparent density of 0.30 g/cm.sup.3 or less and a rebound degree of 50% or more as measured according to ASTM D2632.

The present disclosure relates to a method for physically foaming a polymer material and a foamed article. The method for physically foaming a polymer material comprises: (1) making a thermoplastic elastomer or a polyolefin material into a blank with an injector, an extruder, or a molding press; (2) subjecting the polyolefin blank to a crosslinking reaction to obtain a crosslinked polyolefin blank; (3) subjecting the thermoplastic elastomer blank or the crosslinked polyolefin blank to a high pressure impregnation with a supercritical fluid in an autoclave, then releasing the pressure to a normal pressure to obtain a supercritical fluid-impregnated blank; and (4) placing the supercritical fluid-impregnated blank into an end-product mold to perform an 1:1 in-mold foaming to obtain a finished foam article.

Paving compositions and method of producing the same are provided. In an exemplary embodiment, a paving composition includes a binder, where the binder includes bitumen, recycled plastic, and a performance enhancement additive. The performance enhancement additive is selected from the group of low molecular weight polyolefin, a glycidyl compound, and a combination thereof. The low molecular weight polyolefin has a weight average molecular weight of from about 500 to about 30,000 Daltons. The glycidyl compound includes an ethylene glycidyl (meth)acrylate polymer with a weight average molecular weight of from about 500 to about 30,000 Daltons.

The present invention relates to coated particles in which vegetable wax is provided on the surface of starch particles. The coated particles have an average particle diameter d.sub.1 of 0.5 to 20 ?m and a maximum particle diameter d.sub.2 being less than 30 ?m and less than 4.0 times the average particle diameter d.sub.1. The vegetable wax is contained in an amount of 0.5 to 10.0 wt % in the coated particles. Accordingly, particles having excellent feel characteristics and water repellency can be achieved with a natural material having excellent biodegradability. A method for producing coated particles includes: a step of preparing a dispersion that contains 1 to 20 wt % of starch particles; a step of adding vegetable wax to the dispersion and heating and cooling the mixture to precipitate the vegetable wax on the surface of the starch particles; and a step of subjecting this dispersion to solid-liquid separation to obtain coated particles as a solid.
