Thermoplastic resin composite bead production method, expandable thermoplastic resin composite bead, expanded thermoplastic resin composite bead, and foamed molded article formed from expanded thermoplastic resin composite beads |
摘要 |
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.
