Abstract:
According to the present invention, there is provided a method for producing expandable styrene-modified olefin-based resin particles comprising steps of: impregnating styrene-modified olefin-based resin particles with an easily volatile blowing agent to obtain expandable resin particles, and impregnating 100 parts by weight of the expandable resin particles with 0.1 to 2.0 parts by weight of a surfactant at a temperature of 10 to 30° C. and at a pressure of 0.05 to 0.30 MPa, to obtain expandable styrene-modified olefin-based resin particles.
