Expandable resin particles that have a reduced VOC content, a method of producing the expandable resin particles, and a foamed molded product that has reduced VOC emission are provided. The expandable resin particles contain a base material resin containing, as a structural unit, a styrene unit and an acrylonitrile unit and an expanding agent. The expandable resin particles have a styrene content and an ethylbenzene content each of which is not more than a specific amount.

Foamable resin particles and method of producing same, and foamed molded body

Expandable polystyrene-based resin particles may include a styrene-based monomer, a polysiloxane-containing macro monomer, and a coating composition having a melting point of 40&#xb0; C. or greater. A coefficient of static friction of a foamed molded product, obtained by pre-expanding the expandable polystyrene-based resin particles and molding the pre-expanded expandable polystyrene-based resin particles, may be 4.0 or less. The expandable polystyrene-based resin particles may have a surface layer part that contains polysiloxane as a main component.

Expandable polystyrene resin particles, polystyrene pre-expanded particles, and foam molded body

An expandable poly methyl methacrylate particle including a polymer, which is obtained by a process including polymerizing monomers including 100 parts by weight of an acrylic monomer and from 0.05 to 0.15 parts by weight of a polyfunctional monomer. The acrylic monomer includes 90% to 98% by weight of methyl methacrylate and 2% to 10% by weight of an Calkyl acrylate, relative to a total weight of the methyl methacrylate and the Calkyl acrylate.
