study on synthesis and characterization of unsaturated poly (ester-amide) as bone fixation materials

A new type of unsaturated poly ester-amide was prepared by melt polycondensation and characterized completely. influence of heat treatment conditions and cross-linking content on mechanical and degradation properties of unsaturated polyester-amide were studied. results suggested that the newly synthesized unsaturated poly(ester-amide) possessed good heat stabilization properties. mechanical and degradation properties of cross-linked poly (ester-amide) were determined by heat treatment conditions and cross-linker content. different initiationaccelerating agent systems and their content differences have an insignificant influence on the cross-linking time at room temperature (rt). increasing heat treatment time increased the retention rate of mechanical properties during the degradation process and decreased hydrolysis rate in alkaline solution.
