ABSTRACT:
Process for the dispersion polymerization or copolymerization of olefins, especially ethylene alone or with an .alpha.-olefin, which is conducted in the presence of a surface-active compound containing one or more perfluorocarbon groups and, optionally, one or more hydrophilic groups, to reduce fouling of the reactor with adherent polymer particles. Particularly effective when olefins are polymerized with supported transition metal hydrocarbyl catalysts in non-polar hydrocarbon diluents.
