Document Type and Number:
Japanese Patent JP5795789
Kind Code:
B2
Abstract:
A process for the copolymerization of ethylene and 1-octene to form a copolymer by contacting a mixture comprising ethylene and 1-octene under polymerization conditions with a catalyst composition comprising a metal complex, a cocatalyst and a polymerization modifier, characterized in that, the metal complex comprises a 3-amino- substituted inden-1-yl complex of titanium; the cocatalyst comprises tris(pentafluorophenyl)boron or a trialkylammonium salt of tetrakis(pentafluorophenyl)borate; and the polymerization modifier comprises a compound selected from: the 1:1 molar reaction products of t-butanol with trioctylaluminum; the 1:1 molar reaction products of 2,6-diphenylphenol, 2,6-di(t-butyl)-4-methylphenol, phenol, or t-butyldi(methyl)hydroxysilane with triisobutylaluminum; the 2:1 molar reaction products of di(n-pentyl)amine with triisobutylaluminum; the 2:1 molar reaction products of 2,6-diphenylphenol or t-butyldi(methyl)hydroxysilane with triethylaluminum; the 1:1 molar reaction products of 2,6-diphenylphenol, 2,6-di(t-butyl)-4-methylphenol, phenol, t-butanol, 1-dodecanol, t-butyldi(methyl)hydroxysilane, or p-methoxyphenol with trioctylaluminum; and the 2:1 molar reaction products of 2,6-diphenylphenol, 2,6-di(t-butyl)-4-methylphenol and t-butyldi(methyl)hydroxysilane with tri(octyl)aluminum.
