Title:
SOLID POLYALUMINOXANE COMPOSITION, CATALYST FOR OLEFIN POLYMERIZATION, METHOD FOR PRODUCING OLEFIN POLYMER, AND METHOD FOR PRODUCING SOLID POLYALUMINOXANE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2014/123212
Kind Code:
A1
Abstract:
The purpose of the invention is to provide a solid polyaluminoxane composition suitable as a catalyst support and a cocatalyst of a catalyst for the production of an olefin multimer or an olefin polymer without using silica or another such solid inorganic support. This solid polyaluminoxane composition contains polyalkylaluminoxane and trialkylaluminum, and is characterized in that the solubility in n-hexane at 25°C measured by specific method (i) is less than 0.50 mol%; the solubility in toluene at 25°C measured by specific method (ii) is less than 1.0 mol%; and the molar fraction of alkyl groups derived from the trialkylaluminum part to the total number of moles of alkyl groups derived from the polyalkylaluminoxane part and alkyl groups derived from the trialkylaluminum part in the tetrahydrofuran-d8-soluble fraction, measured by specific method (iii), is 13 mol% or higher.
