DETERMINATION OF BRANCHED CARBON NUMBER-DISTRIBUTION OF POLYACRYLATE BY LIQUID-CHROMATOGRAPHY

This paper deals with the determination of branched carbon number dist ribution of polyacrylate by liquid chromatography after hydrolyzing th e polyacrylate in basic alcohol solution. The products of hydrolysis a re alcohols which can be separated by hot methanol. The long chain alc ohols are oxidized in potassium permanganate and sulfuric acid. The lo ng chain fatty acids thus obtained are derivatized by phenacyl bromide in triethylamine solution. The derivatives were determined by liquid chromatography. (C) 1997 Elsevier Science B.V.
