Polypyrrolidone was thermally degraded in the solid state at 180, 200, 210, and 220°C. Kinetic parameters for overall degradation were determined. Analysis of volatile products showed that 2-pyrrolidone was the major product of decomposition. Infrared analysis of nonvolatile products showed that bands in the region of 900–1130 cm-1 were sensitive to thermal energy. Various possible reactions that lead to the formation of 2-pyrrolidone are discussed briefly.
