Abstract
The invention relates to a blend, based on polystyrene and/or impact resistant polystyrene, which is stress-corrosion, impact and cold resistant and flame retardant. The blend according to the invention contains 50 to 98 mass % of polystyrene or impact resistant polystyrene, 0.01 to 15 mass % of zeolites with a pore size above 0.43 nm, 2 to 18 mass % of a styrene/butadiene block copolymer, 0 to 15 mass % of a flame retardant and 0 to 2 mass % of a surface-active agent. The properties of the blend can be adjusted between wide limits by a suitable selection of the quality and quantity of the components. The blend can be prepared by the processors themselves, whereby the selection of the available polystyrene types can be considerably increased.
