貌似想知道的东西在这一段吧A horizontally disposed, water/steam jacketed, cylindrical stainless-steel autoclave located in a barricade and having a capacity of 36,240 cc and a length-to-diameter ratio of about 1.5 to 1, and provided with a 4-bladed cage-type agitator rotated at 46 rpm and running the length of the autoclave, was evacuated and then charged with 855 grams of paraffin wax, 21.8 kg of demineralized water, and 3.0 grams of ammonium perfluorocaprylate (C-8 APFC) dispersing agent. The autoclave was then heated to 88.degree. C., evacuated and purged with tetrafluoroethylene, after which 0.20 g ammonium persulfate initiator (9.2 ppm) (APS) dissolved in water was added. Then 25 ml of hexafluoropropylene (HFP) was pumped in, and the autoclave was pressured over a period of about 2 minutes to 25.6 kg/cm.sup.2 absolute with tetrafluoroethylene (TFE). Stirring rate and temperature were maintained until polymerization started as evidenced by 0.7 kg/cm.sup.2 drop in pressure. The temperature was immediately raised to 90.degree. C. where it was maintained throughout the polymerization. Additional TFE was then added to maintain the reaction pressure at 25.6 kg/cm.sup.2 until a dispersion of approximately 35 percent solids content (total polymer plus aqueous medium basis) was obtained. After about 1360 grams of TFE had been fed following start of the reaction (4.4 percent solids formed), 1000 ml of 2.7 percent by weight aqueous solution of C-8 APFC dispersing agent was injected continuously at 25 ml/minute into the autoclave to stabilize the dispersion. The TFE feed to the autoclave was terminated after 11,804 grams of TFE was fed, and the pressure was allowed to decrease to 12.3 kg/cm.sup.2 before agitation was stopped and the vapor space of the reactor was vented. The polymerization time from start-up to the time feed was turned off was 57 minutes |
