Chemical Properties
Yellow to light brown crystalline powder
The present invention relates to a novel metallocene compound represented by Chemical formula 1. According to the present invention, the metallocene compound can be used when an olefin-based polymer is produced and has excellent activity. The metallocene
A method for producing an anionized meso-form double-cross-linked ligand represented by formula (3), including: bringing a compound represented by formula (1) into contact with a compound represented by formula (2) at -25°C or less; and introducing an anionizing agent within 5 hours after the contact, wherein R1 to R10 are independently a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms, or the like; A and A' are independently a cross-linking group containing an atom belonging to the 14th group of the periodic table; M and M' are independently an atom belonging to the 1st or the 2nd group of the periodic table.
The ansa-indene ligands {1-Me2Si(3-C9H 6R)2} [R = Me (1), nPr (2), nBu (3), and Bz (4)] were prepared by alkylation of the unsubstituted ansa-indene. These ligands were converted, by reaction with nBuLi, to the
A catalyst activator particularly adapted for use in the activation of metal complexes of metals of Group 3-10 for polymerization of ethylenically unsaturated polymerizable monomers, especially olefins, comprising a neutral (Lewis acid) or charge separated (cation/anion pair) comprising a boron ligand containing a fluorinated organic group containing from 10 to 1000 non-hydrogen atoms.
