A study on the dissolution inhibition of poly norbornene hexafluoroisopropanol in aqueous base solutions

Abstract

It is confirmed that strong inhibitors must not only interact with the polymer but also are highly hydrophobic. A proportional relationship was shown between the inhibition and log P of different additives. In general, PAGs also follow this relationship, however triphenylsulfonium PAGs appear to be less effective inhibitors than bis-tbutylphenyliodonium PAGs having the same anions.
