Polyvinyl Chloride (PVC)? - pictures initiations clothing line
I wonder, could you me a full explanation of the laboratory and the commercial production of polyvinyl chloride? Instead, there are pictures of initiation, propagation and termination (if applicable). Thank you very much.

Polyvinyl chloride, PVC generally short, is also the International Union of Pure and Applied Chemistry (IUPAC) as chloroethanediyl poly ()). This is the third most commonly used thermoplastic polymers for polyethylene and polypropylene.
Polyvinyl chloride is produced by polymerization of vinyl chloride. Since approximately 57% of the mass is chlorine, creating a given mass of PVC requires less petroleum than many other polymers.
The production process is used for suspension polymerization. In this process, the CVM and the water in the polymerization reactor and polymerization is introduced, with other chemical additives are added to initiate the polymerization reaction to. The contents of the reaction vessel is continuously mixed to maintain the suspension and to ensure a uniform particle size of PVC resin. The reaction is exothermic and thus requires a mechanism for cooling the reactor contents at the correct temperature. Since the volume of the contract during the reaction (PVC is denser than the CVM), the water continualland added to keep the mixture of the suspension.
Once the reaction has run its course is, the resulting suspension was degassed to remove PVC and VCM are reduced, which (with the next one in the group will be recycled) and from there through a centrifuge to remove the excess liquid. The sludge is in a bed of hot air dried and sieved the resulting powder before storage or granulation.
