Abstract

N-Isopropyl acrylamide (NIPAM), N, N-dimethyl acrylamide (DMAA), and 2-acetamidoethyl acrylate (AcAMEA) were copolymerized with ethylene employing [(P^ O) PdMe (DMSO)](1- DMSO; P^ O= κ2-P, O-Ar2 P C6H4SO2 O with Ar= 2-MeOC6H4) as a catalyst precursor. Inhibition studies with nonpolymerizable polar additives show that reversible κ-O- coordination of free amide retards polymerization significantly. Retardation of ...
