“Living Polymers” on Polymerization with Extremely Productive Ziegler Catalysts
Abstract
At least 10000 polyethylene molecules per zirconium atom can be obtained with a Ziegler catalyst made up of Cp 2 ZrMe 2 and [Al(Me)O]n. Depending upon the conditions, the molecular weight of the polymer lies between 100000 and 200000. All the results available so far are in accord with the following concept: A molecule of organozirconium compound diffuses into an associate of aluminoxanes. H‐transfer leads to zirconium hydrides which add ethylene to form alkyl compounds and thus give rise to active sites. equation image

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.
