Immortal polymerization: The outset, development, and application
Abstract
The story of the outset of the concept of immortal polymerization is presented. Immortal polymerization is the polymerization that gives polymers with a narrow molecular distribution, even in the presence of a chain transfer reaction, because of its reversibility, which leads to the revival of the polymers once dead, that is, the immortal nature of the polymers. As a result, immortal polymerization can afford polymers with a controlled molecular weight, the number of polymer molecules being more than that of the initiator. The compound that plays a leading role is metalloporphyrin, in which the metal-axial ligand bond has an unusually high reactivity. Immortal polymerization can be carried out in the ring-opening polymerizations of epoxides, episulfides, and lactones by the selection of an appropriate metalloporphyrin as the initiator and a protic compound as the chain transfer agent. Immortal polymerization is an effective method for synthesizing end-functional polymers and oligomers with narrow molecular weight distributions. © 2000 John Wiley & Sons, Inc.

In the citing paper
“The pioneering work of Inoue [147,149] involving the ROP of oxiranes initiated by aluminium porphyrin/alcohol describes an 'immortal' polymerization ; a living polymerization during which the growing chains do not 'die'.”

In the citing paper
“The initiators based on porphyrin complexes or complexes with related structures based on Al, Zn, Y, Lu, In have been used for the polymerization of e.g., oxiranes, thiiranes, lactones, lactides, cyclic carbonates and others [147,149 -156].”

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.
