The at least essentially amorphous polymer resin is preferably polystyrene. The nucleating agent is preferably selected from the group consisting of 1,3:2,4-bis-(benzylidene)-sorbitol derivates and mixtures thereof, and is preferably 1,3:2,4-bis-O-(4-methylbenzylidene)-D-sorbitol, 1,3:2,4-bis-(3,4-Dimethylbenzylidene)-sorbitol and 1,3:2,4-bis-(4-propylbenzylidene)-propyl sorbitol. 112.-. (canceled)15. (canceled) The present invention relates to compositions for the preparation of a polymeric foam with improved thermal properties, and to a foamed polymeric article obtainable therefrom, and to a method for preparing such a polymeric foam or article.In response to environmental concerns, there has been an evolution from using hydrochlorofluorocarbon (HCFC) foam blowing agents to using carbon dioxide and/or hydrocarbons and alcohols. Unfortunately, as a result of this change, the thermal conductivity of foam materials has increased due to the higher conductivity of these new blowing agents. This results in insulation foams that no longer fulfill the required product specifications unless additional steps are taken to increase the thermal resistance of these insulation foams.It is known that an infrared attenuation agent (IAA) can be used to improve an insulation foam. An effective infrared attenuation agent favors increased reflection and absorption and decreased transmission of heat radiation as much as possible. Traditionally, inorganic materials have been used as IAA to reduce the portion of heat radiation. This includes, for example, graphite, aluminum, stainless steel, cobalt, nickel, carbon black, and titanium dioxide. As an example for several ...

Foamed polypropylene-resin particles are obtained by dispersing polypropylene-resin particles containing polyethylene glycol and/or glycerin together with an aqueous dispersion medium in a pressure-resistant container; introducing carbon dioxide gas as a foaming agent into the pressure-resistant container; impregnating the polypropylene-resin particles with the foaming agent under a heating and pressure condition; and then discharging the polypropylene-resin particles into an area having a lower pressure than an internal pressure of the pressure-resistant container and having an atmosphere temperature of higher than 80° C. and not higher than 110° C. The foamed polypropylene-resin particles can yield an in-mold foam molded body at a low heated water vapor pressure for molding, do not lose moldability at a high heated water vapor pressure for molding, have a wide heated water vapor range for molding, exhibit good moldability even when a mold with a complicated shape, a large mold, or a similar mold is used.
