dc.description.abstract |
Polyvinyl chloride is prepared commercially by the free-radical initiated
polymerisation of vinyl chloride. In the suspension process; deionised
water, suspending agents and vinyl chloride monomer (99 wt percent min) are
charged into the polymerizer. The contents, are heated up to 560C before
adding the initiator emulsion.
A conversion of 90 percent is usually achieved after a reaction time of 6-8
hours. Unreacted monomer is stripped off and sent to the monomer recovery
system. tripped PVC slurry is dewatered by using a centrifuge. The PVC
cake is dried and screened to remove oversize resin before packing. |
