Abstract α‐Methylene‐N‐methylpyrrolidone (α‐MMP) was synthesized and homopolymerized by bulk and solution methods. The poly(α‐MMP) is readily soluble in water, methanol, methylene chloride, and dipolar aprotic solvents at room temperature. Thermogravimetric analysis of poly(α‐MMP) showed a 10% weight loss at 330°C in air. The kinetics of α‐MMP homopolymerization and copolymerization were investigated in acetonitrile, using azobisisobutyronitrile (AIBN) as an initiator. The rate of polymerization Rp could be expresed by Rp = k[AIBN]0.49[α‐MMP]1.3. The overall activation energy was calculated to be 84.1 kj/mol. The relative reactivity ratios of α‐MMP (M2) copolymerization with methyl methacrylate (r1 = 0.59, r2 = 0.26) in acetonitrile were obtained. Applying the Q‐e scheme led to Q = 2.18 and e = 1.77. These Q and e values are larger than those for acrylamide derivatives.
