ABS is produced by the mass (or bulk) or emulsion/mass hybrid polymerization of three monomers: acrylonitrile, butadiene, and styrene.   Additionally, pre-polymerized materials can be compounded together to produce ABS.  This technoeconomic report includes production economics for world-scale mass, hybrid, and compounding routes to produce ABS.  The analysis was prepared for plants located in the U. S. Gulf Coast, Western Europe, and Coastal China.
