Effect of ligand backbone substituents of nickel ?-diimine complexes on livingness/controllability of olefin polymerization: Competition between monomer isomerization and propagation.
Original language description
Four ?-diimine nickel complexes [(Ar[BOND]N[DOUBLE BOND]C(R)[BOND] C(R)[DOUBLE BOND]N[BOND]Ar)NiBr2; R[DOUBLE BOND]H, CH3, cyclohexane-1,2-diyl, naphthalene-1,8-diyl, Ar[DOUBLE BOND]2,6-i-Pr2-C6H3-) were investigated in propene and hex-1-ene polymerization to identify the limits of backbone substituent R size needed to provide living/controlled ?-olefins polymerization by the sufficient suppression of ?-H elimination transfer. Propagation kinetics measurements, molar mass on monomer conversion dependencies and reinitiation tests were used to evaluate the livingness of hex-1-ene polymerization. Interestingly, living/controlled hex-1-ene polymerization was observed in the case of all diimine derivatives including the one bearing only hydrogen atom in backbone positions. Unexpectedly, in the case of catalysts bearing H and CH3 backbone substituents, we observed the unusual isomerization of hex-1-ene into internal hexenes in parallel with its polymerization. Nevertheless, by subtracting the amount of monomer consumed in isomerization side reaction, polymerization still keeps the features of living/controlled process.
