摘要：Expanded thermoplastic resinous materials are obtained by mixing styrene-based polymers having mainly a syndiotactic configuration or a thermoplastic resincomposition containing said styrene-based polymer and a foaming agent, and thenheating the resulting mixture. These expanded materials are excellent in heat resistanceand are usefully employed in applications where high heat resistance is needed, e.g., asconstruction materials, buffer materials and so forth.
