Abstract

Polymerization of acrylamide was thermally initiated by the oxygenated cobalt(III) triethylenetetramine complex. Rate, conversion, and molecular weights obtained are favorable comparable to those initiated by K2S2O4 and K2S2O8 initiators. An induction period is about 3 mins. The value of Kdf at 60°C is 6.75 × 10−5 s−1, and the chain transfer to monomer constant is 1.2 × 10−5. The rate dependence obtained are a half order on the initiator concentration and a 1.38 order on the monomer concentration. The mole fraction of combination termination occurred in the overall termination reactions evaluated is 0.746.
