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.
