Abstract

Process for the polymerization of olefins at temperatures of from −20 to 200° C. and pressures of from 0.1 to 20 MPa in the presence of a polymerization catalyst and an antistatic agent, wherein

the antistatic agent is an antistatically acting composition comprising a polysulfone copolymer, a polymeric compound comprising basic nitrogen atoms, an oil-soluble sulfonic acid and optionally a solvent and the polysulfone copolymer, the polymeric compound comprising basic nitrogen atoms and the oil-soluble sulfonic acid constitute together at least 1 wt. % of the antistatically acting composition, and whereinthe antistatically acting composition, when contacted as solution or suspension in heptane, wherein the solution or suspension has a concentration of about 80 g of the antistatically acting composition per liter of heptane, with a 2 M solution of triethylaluminum in heptane at 0° C., generates less than 5 cm3, measured at 23° C. and atmospheric pressure, of ethane per gram of the antistatically acting composition anduse of an antistatically acting composition as antistatic agent for the polymerization of olefins at temperatures of from −20 to 200° C. and pressures of from 0.1 to 20 MPa in the presence of a polymerization catalyst.
