Summary 1. The polyesters formed by ethyleen glycol, 1,6-hexanediol, and 1,10-decanediol with the following dicarboxylic acids have been prepared under identical conditions: oxalic, malonic, succinic, glutaric, adipic, pimpelic, suberic, azelaic, and sebacic acids. 2. Polyesters derived from dicarboxylic acdis having even numbers of carbon atoms have higher melting points than the neighboring pairs of odd-acid polyesters. 3. The solubilities of the polyesters in benzene and alcohol have been determined, and it has been found that the polyesters of the odd dicarboxylic acids have the higher solubilities in alcohol. 4. An explanation has been advanced for the way in which the properties of the polyesters depend on their structures. 5. It has been established that the melting points of polyesters depend not only on the number of methylene groups in the repeating unit, but also on their distribution within the unit.
