Abstract

Direct polycondensation of renewable monomers, itaconic acid and isosorbide, was examined by using various catalysts and radical scavengers. Among the tested compounds, a combination of HfCl4·2THF as a catalyst and galvinoxyl free radical as a radical scavenger was found to yield soluble polymers with relatively high molecular weights without significant isomerization of itaconic acid. The resulting polymers were amorphous, showing a Tg of ~84°C depending on their molecular weights. Treatment of the polymers with benzoyl peroxide gave an insoluble crosslinked polymer. Thus, the polycondensation of itaconic acid and isosorbide could produce sustainable and functional polymers.
