Synthesis and characterization of biodegradable polymer: Poly (ethene maleic acid ester-co-d,l-lactide acid)

A novel biodegradable polymer—poly (ethene maleic acid ester-co-d,l-lactide acid) was synthesized by copolymerizing lactide and prepolymer, which was prepared by the condensation of maleic anhydride and glycol, using p-toluene sulphonic acid as a catalyst, attempting to improve the hydrophilicity, increase flexibility and modulate the degradation rate. FTIR, 1H NMR, MALLS and DSC were employed to characterize these polymers.
