Data confidence 70 medium

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

Thin films of the polyelectrolyte complexes between poly-2-vinylpyridine (poly-2-methyl-5-vinylpyridine) and sodium polystyrenesulphonate (polyacrylic acid) at benzene-water phase boundary have been synthesized. Polycomplex compositions and their stability to action of solvents, temperature and pH have been determined. The behaviour of polycomplexes in mixed organic solvents is compared to predictions of the Dondos-Patterson theory for viscosity of individual polymers in mixed solvents. It allows us to consider the polymer complexes formed on a dimeric interface as new individual nonpolar polymers.
