    Abstract: The present invention is concerned with expanded propylene resin beads including a core layer being in a foamed state and constituted of a propylene-based resin composition (a) and a cover layer constituted of an olefin-based resin (b), the propylene-based resin composition (a) satisfying the following (i) and (ii), and the olefin-based resin (b) satisfying the following (iii) or (iv). (i) A mixture of 75% by weight to 98% by weight of a propylene-based resin (a1) having a melting point of 100° C. to 140° C. and 25% by weight to 2% by weight of a propylene-based resin (a2) having a melting point of 140° C. to 165° C. (ii) A difference between the melting point of the resin (a2) and the melting point of the resin (a1) is 15° C. or more. (iii) A crystalline olefin-based resin having a melting point TmB that is lower than a melting point TmA of the composition (a) and having a relation of 0° C.

    Abstract: Polystyrene-based composite resin particles includes 100 to 500 parts by weight of a polystyrene-based resin with respect to 100 parts by weight of an ethylene-vinyl acetate copolymer resin. The polystyrene-based composite resin particles are impregnated with a volatile blowing agent and are pre-expanded to obtain pre-expanded particles; the obtained pre-expanded particles are immersed in tetrahydrofuran for 24 hours to obtain an extract A; and the pre-expanded particles are divided into two halves through the center to prepare halved particles, and the halved particles are immersed in tetrahydrofuran for 24 hours to obtain an extract B; and the obtained extract A and extract B are subjected to a GPC (gel permeation chromatography) measurement and obtain the following results: the polystyrene-based resin having a weight-average molecular weight (Mw) of 100,000 to 500,000 gives a peak obtained from chromatograms for the extract A and for the extract B.
