Polymethylaluminoxane preparation, method of producing the same, polymerization catalyst, and polymerization method of olefins |
| abstract |
A polymethylaluminoxane preparation exhibiting excellent storage stability with a high yield is provided. A polymethylaluminoxane preparation is formed by thermal decomposition of an alkylaluminum compound having an aluminum-oxygen-carbon bond, the alkylaluminum compound being formed by a reaction between trimethylaluminum and an oxygen-containing organic compound. In this preparation, (i) the oxygen-containing organic compound reacting with trimethylaluminum is an aliphatic of aromatic carboxylic acid represented by the general formula (I), n nR 1 —(COOH) n (I) n n(wherein R 1 represents a hydrocarbon group of C1-C20 straight or branched alkyl groups, alkenyl groups or aryl groups, and n represents an integer of 1 to 5); n(ii) a mole fraction of methyl groups originating from aluminoxane part, relative to the total moles of methyl groups existing in the generated polymethylaluminoxane preparation is not more than 26 mol %; and n (iii) the generated polymethylaluminoxane preparation has a viscosity of not more than 2.1×10 −3 Pa·sec at 40° C. |
