エーテル結合を含む二塩基酸 (第2報)

ジ-, テトラ-, およびペンタエチレングリコールの酸化により得られる二塩基酸のエステル, N-置換アミドの可塑化性

抄録

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.
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).
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).
