Abstract
Process for obtaining adhesion-free thermoplastic masses characterized in that, in a first step, aliphatic, cycloaliphatic and/or aromatic polycarboxylic acids are reacted, containing from 2 to 6 carboxylic groups in the molecule with aliphatic alcohols, monofunctional with 12 to 30 carbon atoms in the molecule, in the presence of an esterification catalyst, such as zinc powder, for a period of time comprised between one and several hours, at a temperature comprised between approximately 150 and 250ºC and, then, it is made reacting the intermediate product obtained with aliphatic diols, for a period of time comprised between one and several hours and under a temperature comprised between 150 and 250º c, the molecular proportions of the reactants being such that, in the product formed the proportion between aliphatic diols, polycarboxylic acids and alcohols take a value of n: n 1: (n 1) m-2n, where n represents an integer between 1 and 11 and m is the functionality of the polycarboxylic acid and, in a second step, the ester mixtures, obtained in the first stage of the process, are combined with thermoplastic masses, which optionally contain chlorine, in a proportion comprised between 0.01 and 5 weight percent, preferably comprised between 0.05 and 2 weight percent.
