Abstract

Product composition of polyglycerol esters, prepared from a direct alkaline polymerization of glycerol followed by esterification with stearic or oleic acids, has been studied. The internal product composition, as analyzed by high performance liquid chromatography (HPLC), shows clearly that in contradiction to what has been published recently, the fatty acid radicals are not distributed at random among all available hydroxyl groups, and thus, any theoretical calculation on the product composition could not be correct. The product composition of the crude material indicates clearly that the internal positions (secondary hydroxyls) of the glycerol polymer are esterified with greater difficulty than the primary hydroxyl groups.
