  • Method for obtaining polymerizable vinyl chloride from a raw product derived from the pyrolysis of 1,2-dichloroethane
    Patent number: 6979754
    Abstract: The invention concerns a method for obtaining directly polymerisable vinyl chloride which consists in subjecting a cooled raw product derived from of pyrolysis of 1,2-dichloroethane, to another cooling process at a temperature not more than 40° C., under pressure ranging between 10 to 15 bars then in leaving it at substantially identical temperature and pressure levels for a duration not more than 20 minutes. The invention also concerns a device for implementing the method.
