Mario Gauthier's research efforts are currently focused on the synthesis and physical characterization of a new class of branched macromolecules, called arborescent polymers. The term arborescent (from the latin arbor = tree) refers to the tree-like or dendritic structure of the molecules. These compounds are obtained in successive reaction cycles of polymerization and grafting. The highly branched structure of arborescent polymers leads to very unusual properties in solution, in the solid state and in the molten state, making them interesting for many specialty applications.
Mario Gauthier teaches both undergraduate and graduate courses. Course offerings have included topics in polymers and polymerization, and macromolecular science.
