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

Phase transitions in polymer-polymer and gel-linear polymer systems consisting of complexes of acrylic acid/butyl vinyl ether copolymers with linear and crosslinked poly-N-vinylpyrrolidone, 1,2,5-trimethyl-4-vinylethynylpiperidinol-4/N-vinylpyrrolidone copolymer with linear and crosslinked polyacrylic acid, polyacrylic acid with crosslinked poly-N-vinylcaprolactam taking place as a function of internal (composition of copolymers) and external (thermodynamic quality of solvents, degree of ionization, temperature) factors have been investigated. In most cases the analogy in behavior of interpolymer complexes in a solution and gel-polymer complexes is observed.
