Abstract: Disclosed is expandable modified resin beads (1), comprising a modified resin as a base resin in which a dispersion phase (3) containing a styrene resin as a major component is dispersed in a continuous phase (2) containing an olefin resin as a major component, and a physical blowing agent. Further disclosed are expanded modified resin beads obtained by expanding the expandable modified resin beads (1), and a foamed molded article formed from the expanded modified resin beads obtained by molding the expanded modified resin beads in a mold. A volume average diameter of the dispersion phase (3) dispersed in the continuous phase (2) is 0.55 μm or more. The expandable modified resin beads (1) have, as a base resin, the modified resin contains 80 to 50 parts by mass of the styrene resin with respect to 20 to 50 parts by mass parts of the olefin resins.

Abstract: A seed beads dispersing disperse system is obtained by dispersing olefin resin seed beads 1 with a specific tubular shape in an aqueous medium. Then, the olefin resin seed beads 1 are impregnated with styrene monomers and the styrene monomers are polymerized in the presence of a polymerization initiator by heating at a temperature in a specified range, to thereby obtain tubular thermoplastic resin composite beads. Expandable thermoplastic resin composite beads obtained by impregnating the thermoplastic resin composite beads with a blowing agent, expanded thermoplastic resin composite beads obtained by foaming and expanding the expandable thermoplastic resin composite beads, and a foamed molded article formed from the expanded thermoplastic resin composite beads by molding are also obtained.
