Abstract: The present invention relates to an ethylene homo- or copolymerization process, characterized in that an inhibitor is added to the reaction mixture or any of its components before the reaction mixture is fed to the reaction zone. The present invention further relates to the use of an inhibitor to reduce fouling in an ethylene homo- or copolymerization process.
Abstract translation: 本发明涉及乙烯均聚或共聚方法，其特征在于在将反应混合物送入反应区之前，将一种抑制剂加入到反应混合物或其任何组分中。 本发明还涉及抑制剂在乙烯均聚或共聚过程中减少结垢的用途。
