Method of producing paraffin wax |
摘要 |
<p>A method of producing a paraffin wax for aqueous dispersion polymerization of TFE which allows high speed aqueous dispersion polymerization of TFE with excellent polymerization behavior such as excellent dispersion stability and consistent production of PTFE having excellent physical properties, and a method of producing PTFE using the paraffin wax. Aqueous dispersion polymerization of tetrafluoroethylene (hereinafter referred to as TFE) is conducted in the presence of a paraffin wax, a polymerization initiator and an emulsifier at least once and then the paraffin wax is recovered. The recovered paraffin wax is used for aqueous dispersion polymerization of TFE in the presence of a polymerization initiator and an emulsifier.</p> |
