Continuous method for determining residual vinyl chloride content in a boiling aqueous polymer dispersion |
摘要 |
An improvement in a process for removing residual vinyl chloride monomer from an aqueous dispersion of a synthetic polymer wherein the dispersion is subjected to boiling conditions while being maintained in a vessel having a vapor space above the liquid level of the dispersion. In the improved process, the content of vinyl chloride monomer in the dispersion is continuously monitored by a boiling point suppression technique.
