Zusammenfassung:The invention relates to foamed plastic which is made of raw materials in parts by weight as follows: 400-600 parts of acrylonitrile, 300-500 parts of methacrylic acid, 10-50 parts of acrylamide, 20-40 parts of an initiator, 50-90 parts of a foaming agent, 10-30 parts of a foaming aid and 1-10 parts of a crosslinking agent. The foamed plastic has excellent mechanical property, heat resistance and forming processing property and is an ideal core material for an engineering structure.
