Summary
2-Oxazolidone was reacted at elevated temperature with adipic, isophthalic or sebasic acid. The reaction products were polymeric in nature and range in color from light tan to dark brown. The polymers were not soluble in most common laboratory solvents with the exception of DMF and DMSO. The polymers had moderate inherent viscosities and 1H-NMR and infrared spectra consistent with a polyester-amide chain structure.
