The effects of the reaction condition were investigated though the polymerization rate, molecular weight of polytetrafluoroethylene (PTFE), and stability of the dispersion. The emulsion polymerization of TFE was different from conventional emulsion polymerization. The polymerization rate was suppressed when ...

about 30 to about 70 weight % non-melt-processible fluoropolymer particles having an SSG of less than about 2.225, said fluoropolymer particles comprising a core of high molecular weight polytetrafluoroethylene and a shell of lower molecular weight polytetrafluoroethylene or modified polytetrafluoroethyl...
The crystallites obtained from the crystallization of the melt of as-polymerized, dispersion grade polytetrafluoroethylene (PTFE) samples in the form of thin films (1 μm) differ in size depending on the molecular weight of the polymer and its thermal history. The production of large crystallite...
The former company also produces cellulose nitrate, polytetrafluoroethylene and polyamide membranes. The minimum value of M̄n measurable by membrane osmometry using these membranes is ca. 1 × 104, and the range of M̄n which can be accurately determined is from 1.5 to 5 × 105. In ...
The non-melt-processible fluoropolymer particles have an SSG of less than about 2.40 and comprise a core of high molecular weight polytetrafluoroethylene and a shell of lower molecular weight polytetrafluoroethylene or modified polytetrafluoroethylene. The mixture is extruded into a coagulation bath ...
