REDUCTION OF POLYMER SCALE FORMATION DURING PVC MANUFACTURE Abstract Use of a small amount of an ammonium or an alkali metal borate as a buffer in the suspension polymerization of PVC to thereby control the pH between about 7.5 and 10,reduces the amount of polymer scale which forms on the inner walls of the reactor. When initiators having a 10 hour half-life at a temperature below about 60°C, such as diisopropyl peroxydi- carbonate (IPP) and t-butyl perpivalate (TBP), are used further reactor cleanliness can be achieved by using them in a solvent comprising a C5-C12 straight or branched hydrocarbon, such as hexane or heptane.
