Polymerization of methyl α-cyanoacrylate—II: Conditions for radical polymerization

The radical polymerization of methyl α-cyanoacrylate containing propane sultone at about 2 × 10^?2 mol dm^?3 can be initiated at 60° by azobisisobutyronitrile or by benzoyl peroxide; the amonic polymerization is not completely suppressed under these conditions but it is of minor importance. The polymer is not soluble in the monomer or in dioxan but polymerizations of the monomer in the bulk or dissolved in dioxan proceed at steady rates in their early stages and have the kinetics characteristic of free radical polymerization.
