Abstract: A foam slab is produced by extrusion (I), with a density of 20-200 g/l and a cross-sectional area of at least 50 cm . This foam is based on styrene polymers and contains 5-50 wt.% styrene- acrylonitrile (SAN) copolymer with an acrylonitrile (AN) content of at least 10 wt.%. Also claimed is the production of (I) by melting a mixture of 90-50 wt.% styrene polymer (PS) and 10-50 wt.% SAN copolymer as above, adding 3-15 wt.% blowing agent, then extruding and expanding the mixture. Preferably the SAN is a binary copolymer of 90-50 wt.% styrene and 10-50 wt.% AN, or a graft copolymer of styrene and AN on a rubber-elastic polymer. Preferred blowing agents are mixtures of halogen-free blowing agents containing at least 5 wt.% carbon dioxide.
