It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Abstract With the methods of sedimentation, fractionation, and viscosimetry the influence of the reaction conditions on the molecular weight distribution of alicyclic polyimides is investigated. Under homogeneous conditions the most probable distribution occurs, whilst in the case of a two‐phase system the molecular weight distribution tends to narrow in comparison with the most probable one. The obtained data are in good agreement with the theory of the two‐phase polycondensation.
