FI Catalysts: Unique Olefin Polymerization Catalysis for Formation of Value-added Olefin-based Materials
FI catalyst Olefin polymerization Polyolefin Olefin-based material Block copolymer Supported catalyst
2010/9/8
This review describes the olefin polymerization behavior of bis(phenoxy-imine) and bis(phenoxy-ketimine) early transition metal complexes (a.k.a. FI catalysts). FI catalysts display unique catalytic p...
Active Catalyst Derived from Nb-containing Heteropoly Acids: Their Acid Properties and Catalysis in Friedel-Crafts Reactions
Heteropoly acid Friedel-Crafts reaction Support effect NMR EXAFS Temperature programmed desorption
2010/9/8
A ternary-mixed oxide catalyst, H3PO4-WO3-Nb2O5, was prepared with the evacuation of a mixed solution of phosphoric acid, niobic oxalate, and (NH4)10W12O41, followed by calcination in air. We found th...
