Abstract
Correction for ‘Synthesis and properties of block copolymers composed of norbornene/higher α-olefin gradient segments using ansa-fluorenylamidodimethyltitanium-[Ph3C][B(C6F5)4] catalyst system’ by Haobo Yuan et al., Polym. Chem., 2021, DOI: 10.1039/d0py01370f.
The authors regret a mistake in reporting the content of diblock and triblock in each post polymer in the “Synthesis of block copolymers” section. The sentence should read:
The weight fractions of the prepolymer and the block copolymer in the post polymers were calculated from the relative areas of the fitting curves of the molecular weight distribution (Fig. S2, Table S1†), which indicates that the content of diblock and triblock in each post polymer was 83–89 wt% and 68–69 wt%, respectively.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
