Abs Resins

Abstract

The emulsion route to ABS involves the preparation of rubber latex - usually non-stereospecific polybutadiene. This latex is emulsified with styrene, acrylonitrile, and other components at a pH of 10-10.5 and 57-60oC. Residence time in the reactors is 100-120 minutes. The resin latex is then coagulated and the ABS removed from the resuIting mixture. The remaining operations dry, compound, and convert the resin to a saleable form.
