Abstract

N-Acryloyl-N'-phenylthiourea (APTU) is polymerized by a free-radical mechanism. The polymer formed has low molecular weight. APTU is capable of polymerization in the solid state and undergoes cyclization in solution. APTU was copolymerized with styrene (St), vinyl acetate (VA), acrylonitrile (AN), and methyl methacrylate (MMA). The reactivity ratios have been calculated in each case by several methods. A unique set of Q-e parameters has been calculated by a least-squares method. The thermal stability of the St-APTU and AN-APTU copolymers was found to decrease with increasing APTU contents
