Atom transfer radical polymerization (ATRP) is a technique for the controlled<br/>polymerization of various olefins. Traditional catalysts systems for ATRP are copper-<br/>based coordination complexes, but transition metals and copper mining are known to have adverse impacts on the environment. This study focuses on utilizing two novel aluminum-based coordination complexes as inexpensive and friendly alternative catalysts systems. The two catalysts used here are Al-alpha-diimine complexes that are expected to exhibit 1-electron redox processes that can be exploited for ATRP of several different monomers. The efficacy and selectivity of these catalysts was investigated by varying the identity of the olefinic monomer, initiator, and solvent used for the polymerization reaction.
