Pyromellitic dianhydride (compound 1) was reacted with L-methionine (compound 2) in acetic acid and the resulting imide-acid [N, N＇-(pyromellitoyl)-bis-L-methionine diacid] (compound 3) was obtained. The compound 3 was converted to the [N, N＇-(pyromellitoyl)-bis-L-methionine diacid chloride (compound 4) by reaction with thionyl chloride. A new facile and rapid polycondensation reaction of compound 4 with ethylene dimine was reacted by microwave heating. The polymerization reaction proceeded rapidly and was completed within 10 minutes, producing chiral polymer[poly(N, N＇-(pyromellitoyl)-bis-L-methionine oxalamide)](polymer 5). The structure of products was characterized by IR and 1H-NMR. The experimental results show that a synthesis foundation of chiral polymer was provided by introducing L-methionine into the polymer by microwave heating.
