Abstract
The rate of polymerization of acrolein oxime initiated by n-butyllithium has been studied at temperatures ranging from 20 to 50°C. The characteristic time—conversion curves obtained depended on the type of solvent used: The acceleration of reaction was initially observed in the bulk polymerization. The use of dichloroethane as a solvent gave a linear relationship of time—course, whereas polymerization in tetrahydrofuran was violent at the initial stage and afterward proceeded at a constant rate. The initial rate was proportional to the square root of the concentration of butyllithium for the bulk polymerization, whereas for the solution polymerization, the rate was proportional to the first power of the concentrations of both the n-butyllithium and acrolein oxime. A consistent explanation for this polymerization behavior is as follows: (1) The polymerization involves no termination process and a stable polymer is produced only by a chain transfer reaction with acrolein oxime. (2) The polymerization proceeds through an initiation step by a reaction of n-butyllithium with acrolein oxime, each of which has different aggregation factor depending on the kind of solvent used.
