Process Economics Program Report 13E
Published: Oct-91
This supplementary report reviews recent technical developments in the manufacture of polyvinyl chloride (PVC) resins by the suspension, bulk, emulsion, microsuspension and solution processes; the prevention of polymer encrustation on the surfaces inside the reactor; and the removal of the residual monomers from the reaction products. The report also evaluates the process economics of various grades of PVC resin by the suspension, bulk, emulsion and micro-suspension processes. We consider production by the suspension process of the following grades:
- general-purpose
- high bulk density
- skinless
- low molecular weight
- ultra-high molecular weight
- high-volume resistivity
- radiation resistant.
We evaluate new liquid-phase bulk process technology,
which employs a spherical polymerizer in place of the vertical polymerizer.
In the production of dispersion resins, we include the batch, continuous and
seeded batch emulsion processes, as well as the batch and seeded batch micro-suspension
processes.
