    • Disclosed are compounds useful as catalyst activators for olefin polymerization, comprising structures of the following formulae: wherein: L+ is a protonated derivative of an element of Group 15 of the Periodic Table of the Elements, additionally bearing two hydrocarbyl substituents of from 1 to 50 carbons each, or a positively charged derivative of an element of Group 14 of the Periodic Table of the Elements, said Group 14 element being substituted with three hydrocarbyl substituents of from 1 to 50 carbons each; R1 is a divalent linking group of from 1 to 40 non-hydrogen atoms; R2 independently each occurrence is a ligand group of from 1 to 50 nonhydrogen atoms with the proviso that in a sufficient number of occurrences to balance charge in the compound, R2 is L+—R1—; M1 is boron, aluminum or gallium; Arf independently each occurrence is a monovalent, fluorinated organic group containing from 6 to 100 non-hydrogen atoms; Y is a Group 15 element; and Z is a Group 14 element.
    • 公开了可用作烯烃聚合的催化剂活化剂的化合物,其包含下式的结构:其中:L +是元素周期表第15族元素的质子化衍生物,另外带有1至50个碳的烃基取代基 每个元素或元素周期表第14族元素的带正电荷的衍生物,所述第14族元素被各自为1至50个碳的三个烃基取代基取代; R 1为1至40的二价连接基团 非氢原子; R2各自独立地为1至50个非氢原子的配体基团,条件是在足够数量的化合物中平衡电荷的情况下,R2为L + -R1-; M1为硼,铝或 镓; Arf各自独立地为含有6至100个非氢原子的单价氟化有机基团; Y为第15族元素; 而Z是第14组元素。
