Process of polymerizing vinyl chloride with washing of charging passage |
摘要 |
A process of preparing a vinyl chloride polymer in a polymerization vessel comprising the steps of: charging a polymerization initiator through a charging passage communicating with the inside of the polymerization vessel, and polymerizing vinyl chloride or a vinyl monomer mixture containing vinyl chloride in an aqueous medium, wherein after said polymerization initiator has been charged into the polymerization vessel, said charging passage is washed with a cleaning fluid containing a polymerization inhibitor. This process can effectively prevent scale formation in the charging passage and produce a vinyl chloride polymer of high quality.
