Pre‐Rate‐Determining Selectivity in the Terpolymerization of Epoxides, Cyclic Anhydrides, and CO2: A One‐Step Route to Diblock Copolymers
Abstract
Catching a second wind: In kinetic resolution polymerization, one monomer is consumed faster than the other, which creates diblock copolymers that only slowly approach 100 % conversion and contain tapering. In the title reaction, the opposite is true: the first block forms cleanly, followed by a second block that has an even higher rate of polymerization. This unique reaction allows for the programmed self-assembly of diblock polymers that display little tapering.

This selectivity is attributed to the faster rate of anhydride insertion than CO2 insertion into the metal-alkoxide intermediate.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
