Process for producing a tetrafluoroethylene polymer excellent in strenght |
摘要 |
<p>A process for producing a tetrafluoroethylene polymer, which comprises polymerizing tetrafluoroethylene in an aqueous medium in the presence of a dispersant, a stabilizer and a polymerization initiator, wherein the polymerization initiator is a redox polymerization initiator comprising a halogen acid salt YXO3/a sulfite Z2SO3 wherein X is a chlorine atom, a bromine atom or an iodine atom, Y is a hydrogen atom, ammonium, an alkali metal or an alkaline earth metal, and Z is ammonium, an alkali metal or an alkaline earth metal. By this process, it is possible to obtain a tetrafluoroethylene polymer which is suitable for a stretching operation after paste extrusion.</p> |
