Coordination polymerization of polar vinyl monomers (or functionalized alkenes) by discrete, single-site metal catalysts has attracted ever growing interest due to its precision in the catalyst-based stereochemical and architectural control as well as its ability to produce new classes of polymeric materials unattainable by other means of polymerization. This presentation will focus on coordination-addition polymerization of polar vinyl monomers by discrete or hybrid early-metal, main-group, and lanthanide catalysts. Specifically, chiral metallocene cations, discrete main-group anions, and their dually active ion pairs, as well as nucleophile/electrophile pairs and classical or frustrated Lewis pairs have enabled the development of five types of polymerizations of polar vinyl monomers including naturally renewable feedstocks: stereospecific & living coordination polymerization, asymmetric coordination polymerization, single-site anionic polymerization, bimolecular polymer-transfer polymerization, and diastereospecific ion-pairing polymerization.
Professor Eugene Y.-X. Chen has authored or co-authored approximately 77 publications (including 2 Chem. Rev,15 JACS,) and 21 patents.
