Patent ID: 8147768

Claim:
A system configured to produce polyvinyl chloride, the system comprising: a high shear mixing device comprising at least one rotor/stator set and configured to produce a polymerization mixture by high shear mixing a vinyl chloride solution with an initiator solution, wherein the polymerization mixture comprises an emulsion of droplets; a pump in fluid communication with an inlet of said high shear mixing device via a high shear device inlet line, wherein the pump is fed via a pump inlet line; a vessel in fluid communication with an outlet of said high shear mixing device and configured for maintaining a predetermined pressure and temperature on the polymerization mixture, wherein the vessel comprises an outlet for a product comprising polyvinyl chloride and unconverted vinyl chloride and a vent gas outlet for at least one gas selected from the group consisting of gaseous vinyl chloride, volatile reaction products, and combinations thereof; wherein said vessel comprises a batch process tank reactor, and a processing device positioned downstream of the vessel and configured to reduce the content of unconverted vinyl chloride in the product.
