How this score is calculated

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

Copolymers of acrylic acid and vinylbutyl ether AA/VBE) have been involved in complexation reactions with non-ionic poly-N-vinylpyrrolidone (PVP), polyethylene glycol (PEG) and cationic poly-N-methyl-4-vinylethynylpiperidinol-4 (PVEP) and polyvinyl ether of monoethanolamine (PVEMEA) polymers. Interpolymer complexes (IPC) are stabilized due to the formation of either cooperative system of hydrogen or ionic bonds depending on the nature of interacting macromolecular components. The stoichiometry of IPC was determined by electrochemical methods. The stability of IPC depends on thermodynamic quality of the solvents, temperature, and degree of ionization. The permeability of IPC membranes with respect to urea was studied. Copyright © 2000 John Wiley & Sons, Ltd.
