Title:
15族化合物から誘導されるオレフィン重合助触媒及びその使用法
Document Type and Number:
Japanese Patent JP2004500359
Kind Code:
A
Abstract:
Fluorinated amine compounds, R'iArF-ER2, where ArF is a fluo-roaryl substituent, E is nitrogen or phosphorous, each R is independently a C1-C20 hydrocarbyl substituent, or the two R's may be connected to form an unsubstituted or substituted C2-C20 cycloaliphatic substituent, R' is a C1-C20 hydrocarbyl or halogenated hydrocarbyl, and i is 0, 1 or 2 are disclosed. These compounds may be protonated and complexed with suitable substantially noncoordinating anions to prepare polymerization catalyst components. When these catalyst components are combined with organometallic catalyst precursors, the catalyst precursor is activated to a catalyst. This catalyst is combined with monomer under olefin polymerization conditions to prepare polymer. High number-average molecular weight polymers at high productivity rates were observed from using metallocene catalysts activated with [N-pentafluorophenyl pyrrolidinium] [tetrakis(pentafluorophenyl) borate].
