摘要: The present invention relates to catalysts component for the polymerization of ethylene and its mixtures with olefins CH
2 =CHR, wherein R is an alkyl, cycloalkyl or aryl radical having 1-12 carbon atoms, comprising Ti, Mg, halogen, and electron donor belonging to 1,2-diethers as internal electron donor compound. The catalyst of the invention is suitably used in (co)polymerization processes of ethylene to prepare (co)polymers having narrow Molecular Weight Distribution (MWD) and high bulk density.摘要翻译: 本发明涉及用于乙烯及其与烯烃CH 2 = CHR的混合物聚合的催化剂组分,其中R为具有1-12个碳原子的烷基,环烷基或芳基,包含Ti,Mg,卤素和电子给体 到1,2-二醚作为内部电子给体化合物。 本发明的催化剂适合用于乙烯的(共)聚合过程以制备具有窄分子量分布(MWD)和高堆积密度的(共)聚合物。
