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

Polystyrene suspensions with an average particle diameter of 0.1–0.25 μm and a narrow particle size distribution were synthesised in the presence of a mixture of surfactants – sodium alkyl sulphonate (E-30), oxyethylated sulphated alkylphenol (AP-9), and organosilicon surfactant α,ω-bis[10-carboxydecyl] polydimethylsiloxane (CS). It was shown that the absence of a highly disperse particle fraction in the suspension is observed only when the polymerisation of styrene is carried out with an ionogenic surfactant content close to the critical micelle concentration (CMC).
