Cyclo‐depolymerisation of polyundecanoate and related polyesters: characterisation of cyclic oligoundecanoates and related cyclic oligoesters

Ruddick, Clare L., Hodge, Philip, Zhuo, Yang, Beddoes, Roy L., Helliwell, Madeleine·1999·Journal of Materials Chemistry

Abstract

The cyclo-depolymerisation of linear polyundecanoate has been studied in detail. The cyclic oligomers produced were characterised by gel permeation chromatography, 1 H NMR spectroscopy and mass spectroscopy in comparison with the corresponding linear oligomers. A sample of the cyclic dimer was isolated and its crystal structure determined. Cyclic oligooctanoates, oligodecanoates and oligododecanoates were prepared similarly. The ring-opening polymerisation of the cyclic oligoundecanoates was briefly investigated.

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.
