New Titanium(IV)-Alkoxide Complexes Bearing Bidentate OO Ligand with the Camphyl Linker as Catalysts for High-Temperature Ethylene Polymerization and Ethylene/1-Octene Copolymerization
04/11/2022 - In order to increase the thermal stability of olefin polymerization precatalysts, new titanium(IV) complexes with diolate ligands differing in the degree of steric hindrances were synthesized from...
Slow-chain-walking polymerization of ethylene and highly chain-straightening polymerization of 1-hexene to access semicrystalline polyolefins
- The production of semicrystalline polyolefins using ?-diimine late transition metal catalysts is highly desired but challenging in both ethylene and ?-olefin polymerization, which relates to...
Post-metallocene catalysts for the synthesis of ultrahigh molecular weight polyethylene: Recent advances
- This review summarizes the progress of transition metal catalyzed ethylene polymerization to ultra-high molecular weight polyethylene (UHMWPE), focusing on the catalytic activities of different...
