Figure 4.
DSC data for thermoplastic 10% PETA samples containing 0, 1000, and 10,000 ppm benzoquinone. As inhibitor composition increased, the exotherm onset, which corresponds to the thermally-induced onset of the auto-polymerization reaction of the acrylic double bonds in the PETA molecules, increased from 120°C to 131°C to 142°C.
