AbstractThe polymerization ofN‐vinylcaprolactam in toluene, dioxane, chlorobenzene, dimethylformamide, and ethylene carbonate with various peroxides, perbenzoates and azobisisobutyronitrile as initiators at 60–80°C, was studied. Under these conditions azobisisobutyronitrile andtert‐butyl perbenzoate have satisfactory activity as initiators. Under these conditionsN‐vinylcaprolactam polymerization in homogeneous solution is first order towards the monomer and 0.5 order towards the in
