EXPANDED COMPOSITE POLYSTYRENE RESIN PARTICLES AND MOLDED FOAM THEREOF

摘要

Expanded composite polystyrene resin particles which each have a plurality of cells and comprise membranes which separate the plurality of cells, the membranes comprising a polystyrene resin that constitutes a continuous phase and fine poly(alkyl acrylate) resin particles that have been dispersed in the continuous phase and constitute a dispersed phase, the polystyrene resin having been combined with the fine poly(alkyl acrylate) resin particles, wherein the dispersed phase is present in the form of a plurality of layers stacked in the thickness direction of the membrane in a section of each membrane of the expanded composite polystyrene resin particle.
