[0198] 1. Preparation of PBPE
[0199] Two PBPEs were prepared using hafnium metal complexes of polyvalent aryloxyether catalysts.
[0200] Catalyst B is a hafnium metal complex of a polyvalent aryloxyether catalyst, which is [[2',2"'-[1,3-propanediylbis(oxyl-KO)]bis-{3-[ 9H-3,6-bis-(1,1-dimethylethyl)-carbazol-9-yl]}-5'-fluoro-5-(1,1,3,3-tetramethylbutyl )-[1,1'-biphenyl]-2-hydroxyl-KO]](2-)]dimethyl hafnium.
[0201] Table 1 below provides the name and structure of Catalyst B.
[0202] Table 1 - Hafnium metal complexes of polyvalent aryloxyether catalysts
[0203]
[0204]Each PBPE is made according to the following procedure. Catalyst B and co-catalyst component solutions were metered using pumps and mass flow meters and combined with the catalyst rinse solvent and introduced into the bottom of the reactor. The co-catalyst used is a long-chain alkyl ammonium borate approximately equal in stoichiometry to methyl di(octadecyl) ammonium tetrakis(pentafluorophenyl) bora...
