Abstract

Correction for ‘Axial-phenyl-constrained bis(imino)acenaphthene-nickel precatalysts enhance ethylene polymerization’ by Quanchao Wang et al., Polym. Chem., 2024, https://doi.org/10.1039/d4py01110d.

The authors regret that an incorrect version of Table 5 was included in the original article. The correct version of Table 5 is presented below. The authors note that the correction does not change the conclusions of the paper.
Table 5 Branching analysis, density, mechanical characterization, and other parameters of selected samples
PE samplea M w[thin space (1/6-em)]b M w/Mn[thin space (1/6-em)]b T m[thin space (1/6-em)]c (°C) Branchesd (B/1000 C's) Density (g cm−1) Stresse (MPa) Straine (%) SRf (%) Details
a The rule of naming: PEcomplex-temperature-activator and ratio. For example, PENi2-60-M1 means the PE produced by Ni2 under the temperature of 60 °C and the MMAO/Ni ratio of 1000. b M w (kg mol−1), Mw and Mw/Mn determined by GPC. c Determined by DSC. d Data determined from the 13C NMR spectrum using approaches described by Galland et al.63 e Data was gained from monotonic tensile stress–strain tests. f Strain recovery values (SR) were calculated by using the standard formula SR = 100(εa − εr)/εa, where εa is the applied strain and εr is the strain in the cycle at 0 loads after 10 cycles.
