| 摘要 |
Polytetrafluoroethylene dispersions obtained from dispersion polymerization which have high solids content and small polytetrafluoroethylene particles are obtained by employing a combination of disuccinic acid peroxide and an inorganic persulfate, and a combination of an anionic and a hydrocarbon dispersing agent, precharged to the polymerization mixture, and by adding a combination of disuccinic acid peroxide and an anionic dispersing agent during the course of the polymerization.
