This report deals with the preparation of some esters and N-substituted amides of the following three dibasic acids, di (carboxy) methyl ether, di (carboxymethoxy) ethyl ether, di [β- (carboxy-methoxy) ethoxy] ethane, which were respectively obtained from di-, tetra-, and penta-ethyleneglycols by the oxidation with nitric acid; and also deals with the study on their charateristics as plasticizers for polyvinyl chloride resins.<BR>Esters, mentioned above, were generally excellent in low temperature performance and also gave good antistatic properties to the plastics. But the resins plasticized with those esters exhibited a poor thermal stability (Table-4).<BR>N-substituted amides didn't seem to be good plasticizers because of the low compatibility with resins and especially in the poor thermal stability (Table-5).
