Abstract
The effect of oxygen on the polymerization of acrylonitrile(AN) initiated by ceric ion was investigated. The results obtained are as follows: 1) Ceric salt initiates the polymerization of AN after some induction period in the presence of oxygen in aqueous solution, and the yield of polymer increases with increasing oxygen content(Fig.2, Fig.3).2) The oxygen in aqueous solution is almost consumed during induction period(Fig.6).3) The ceric ion in aqueous solution is not consumed by monomer during induction period, but begins to decrease its concentration after the initiation of polymerization(Fig.7).From these results, oxygen in water was found to take part in the initiation of polymerization, and it is assumed that oxygen reacts with monomer in the presence of ceric salt to form primary radical.
