Process for the in-situ preparation of single-site transition metal catalysts and polymerization process
Abstract:
The invention relates to a process for the in-situ preparation of alkylated single-site transition metal catalysts by contacting a precatalyst with an alkylating agent in the presence of one or more olefin monomers in the polymerization system. The precatalyst, which is produced prior to introducing into the polymerization system, is obtained by contacting a transition metal complex and boron-containing ionizing agent, optionally, with a support.
Abstract(Chinese):

本发明涉及一种通过在聚合体系中在一种或多种烯烃单体存在下使预催化剂与烷基化剂接触来原位制备烷基化单点过渡金属催化剂的方法。 在引入聚合体系之前产生的预催化剂是通过使过渡金属络合物和含硼离子化剂任选地与载体接触来获得的。
