摘要： 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.

摘要： 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° 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.

摘要： A method for producing expandable polystyrene-based resin particles, the method including producing polystyrene-based resin particles that comprise a styrene-based monomer and a polysiloxane-containing macro monomer, and impregnating an expanding agent into the polystyrene-based resin particles to produce the expandable polystyrene-based resin particles. The production of the polystyrene-based resin particles comprises the simultaneous addition of an initiator and the polysiloxane-containing macro monomer. The initiator causes the generation of one or more of an alkoxy radical and a carbonate radical.
