A process for the preparation of polyolefins, wherein the polymerization is carried out in the presence of an antistatic agent comprising an alkylene oxide derived polymer comprising an average of 10 to 200 repeating units-(CH 2 - CHR-O)-, R is an alkyl group having hydrogen or having 1 to 6 carbon atoms, wherein the alkylene oxide derived polymer is a random copolymer of ethylene oxide and other alkylene oxides, and is derived from epoxy The ratio n:m of ethane-derived repeating units-( CH2 - CH2 -O)- to repeating units-( CH2 -CHR'-O)- derived from other alkylene oxides is in the range from 6:1 to 1: 1, wherein R' is an alkyl group having 1 to 6 carbon atoms and all end groups of the alkylene oxide derived polymer are -OH groups. |
