ABSTRACT:
Particulate polytetrafluoroethylene dispersion resin characterized by high molecular weight, relatively large particle size, uniform spherical particle shape and narrow particle size distribution, which is suitable for making stable concentrated aqueous polytetrafluoroethylene dispersions of concentrations higher than heretofore available, is made by polymerization of tetrafluoroethylene in aqueous dispersion in the conjoint presence of fluid octafluorocyclobutane and certain polyfluorinated carboxylic acid salt dispersing agents, using water-soluble peroxide initiators.
