A new type of unsaturated poly(ester-amide) was prepared by melt polycondensation and characterized after sealed end with benzyl alcohol by Fourier transform infrared spectroscopy, gel permeation chromatography (GPC) and thermal gravimetric analysis (TGA). The compressive strength of unsaturated poly (ester-amide) with different heat treatment conditions was measured after depth cross-linked. The degradation properties of depth cross-linked unsaturated poly(ester-amide) were studied in pH 7.4 phosphate buffer at 37 degrees C and the compressive strength loss was measured. Hydrolysis behavior of depth cross-linked unsaturated poly(ester-amide) was also carried out in 1.0 mol/L NaOH standard solution at room temperature. All the preliminary results suggested that the copolymer might be potentially used as a new type of bone fixation material.
