Unformatted text preview: monomers and the manner in which they are assembled in the final product can be varied considerably. Thus commercial ABS polymers are available with appreciable differences in properties, but they are generally characterized by high impact strengths and softening points as high as, or higher than, straight polystyrene. In genenal, emulsion process is used to make materials of high impact strength, and bulk and suspension processes are preferred for the materials with less impact strength. The physical properties are the reflection of polymer morphology. The emusion process produce the ABS product containing solid rubber particles with the size about 0.1 um in diameter. On the other hand, the suspension (bulk) produce ABS with much larger overall rubber particle size, up to 1 mm in diameter, with the sub-enclosed SAN in the rubber domains....
