Abstract:
This paper presents the thermal analysis with thermogravimetry (TG) techniques of some triesters of citric acid (2-hidroxy-1,2,3 propane tricarboxylic acid) by taking into account aliphatic alcohols from C2-6, iso C10 and iso C13 along with a special alcohol of a complex aliphatic-aromatic structure, namely 2-[(p-nonyl) phenoxy] ethanol. By varying the relationship between these alcohols, two series of products have been realized with role in polymeric packaging. The natural source of the citric acid promotes a presumable and adequate biodegradability potential.
Keywords:
