Polyesteramides derived from bis-oxamidodiols and dicarboxylic acids

摘要

Alternating esteramide polymers are obtained from the reaction of bis-oxamidodiols such as N,N'-bis( omega -hydroxyalkylene)oxamide with a dicarboxylic acid or diesters such as diethyl oxalate, diethyl succinate, diethyl suberate, or dimethyl terephthalate. The polymers are obtained in good yield and have film- and fiber-forming properties. Some polymers are absorbable in biological systems and are useful as absorbable surgical devices. Other of these polymers are nonabsorbable and are useful as textile fibers.
