“Living” Free Radical Ring-Opening Polymerization of 5,6-Benzo-2-methylene-1,3-dioxepane Using the Atom Transfer Radical Polymerization Method

Yuan, Jin-Ying, Pan, Cai-Yuan, Tang, Ben Zhong·2001·Macromolecules

Abstract

To clarify whether atom transfer radical polymerization can be extended to free radical ring-opening polymerization, the polymerization of 5,6-benzo-2-methylene-1,3-dioxepane (BMDO) was carried out in the presence of ethyl α-bromobutyrate/CuBr/2,2‘-bipyridine. The structure of poly(BMDO) was characterized by 1 H and 13 C NMR spectroscopy as well as gel permeation chromatography. The living polymerization of BMDO was identified by the following facts: a straight line of ln([M] 0 /[M]) versus polymerization time, linear increase of molecular weight with increasing conversion, and narrowing polydispersity. The mechanism of living free radical ring-opening polymerization was discussed.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • By varying the monomers or their proportions, or the mode of initiation (NMP, RAFT or ATRP), many and varied polymers can be obtained, optimized for agricultural, medicinal or pharmaceutical fields.

    “It is clear that by varying the monomers or their proportions, or indeed by varying the mode of initiation, e.g., NMP (nitroxide mediated polymerization) [35], RAFT (reversible addition fragmentation transfer polymerization) [36] or ATRP (atom transfer radical polymerization) [37] many and varied polymers can be obtained, optimized for their use in agricultural, medicinal or pharmaceutical fields.”

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.
