摘要:

AbstractMaleic anhydride (MA) reacts in acetone solution with pyridine (Py) at room temperature with carbon dioxide evolution and formation of oligomers having average M̄nranging from 400 to 700 daltons. The influence of pyridine concentration on the rate of decarboxylation has been studied. The product obtained with molar ratio MA/Py = 1.64 is very reproducible. This product has been characterized with different analytical techniques. The results obtained allowed us to propose a reaction scheme for the oligomerization
