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 Complex formation between poly(ethylene glycol) and 4‐nitrophenol in solutions and melts was investigated by potentiometric and conductometric titration, IR spectroscopy and thermal analysis. It is shown that the interaction of the polymer with the low molecular compound is carried out through hydrogen bonds between the oxygen atoms of the polymer and the hydroxyl groups of 4‐nitrophenol. It depends on the molar ratio of the components and on the temperature of the solution.
