Experimental investigation of vinyl chloride polymerization at high conversion—reactor dynamics

Abstract A series of suspension polymerizations of vinyl chloride monomer (VCM) was carried out in a 5‐L pilot plant reactor over the temperature range, 40–70°C. The reactor pressure and monomer conversion were monitored simultaneously every 7–8 min. The critical conversion X f , at which the liquid monomer phase is consumed, was considered to occur when the reactor pressure fell to 98% of the vapor pressure of VCM for suspension at the …
