Research

Professor Sogah and group's interest lies in the development of cost-effective, one-pot chemistry that uses cationic, anionic, free radical, and step-growth polymerizations in an orthogonal fashion. This approach relies on a multifunctional initiator containing initiating sites for each method and has led to the synthesis of novel functional macromonomers. In living free-radical polymerization, they are investigating novel functionalized nitroxyl radicals that operate at lower temperatures and can tolerate a broad scope of monomers. In their continuing studies of GTP, they are probing control of stereochemistry and regio-chemistry using cyclopolymerization, chiral monomers and initiators.
