This report reviews the commercial and technical developments in polystyrene that occurred from mid-1968 to about Fall, 1973. It presents the cost estimates for the production of polystyrenes by the bulk-press polymerization process and the bulk-suspension polymerization process, the production of polystyrene foams by the vacuum preexpansion process, and the production of polystyrene foam sheets by the direct- injection, tandem extrusion process. Biaxial orientation of polystyrene sheets and films and the preparation of polystyrene structural foams are also reviewed, but cost estimations are not given because they may be included in other PEP reports on synthetic papers and foamed plastics.
