- Abstract
The microwave-assisted polycondensation of maleic anhydride and 1,6-hexanediol was carried out using p-toluenesulfonic acid as catalyst. The resulting unsaturated polyester was characterized using Fourier transform infrared (FTIR) and 1H NMR spectroscopy, and the molecular weight determined using gel permeation chromatography. 4,4′-Decanediyldioxydi( N-methyl- p-phenylenenitrone) was chosen as a model compound for the crosslinking of the unsaturated polyester. The crosslinking, which is known to proceed via 1,3-dipolaric cycloaddition, was followed using differential scanning calorimetry. Additionally, the kinetics of the cycloaddition was evaluated at 120 °C using FTIR spectroscopy. Copyright © 2012 Society of Chemical Industry
