Abstract
The solid-state polymerization of itaconic acid (IA) was investigated with and without the catalyst (dibutyl peroxide) at 100, 120, and 150°C, respectively. The reaction products were identified as oligomers by elemental, infrared, and liquid chromatographic analyses. The relation between the crystal structure of IA and its reactivity in the solid state was also studied. It was deduced that the spacing and the angle between olefinic π-orbitals of adjacent vinyl groups, the conformation of the molecules, and the kinks of hydrogen bonds are probably the most important factors for determining the reactivity of the monomer in the solid state.
