Processability Map of a Recyclable Thermoplastic for Structural Applications. Kinetics of Induction Period

In this study, we conducted a comprehensive kinetic analysis of the polymerization and thermal decomposition of an acrylic thermoplastic to establish a time-temperature-transformation (TTT) processability map. The process exhibits an induction period followed by rapid polymerization, indicating a complex mechanism. We introduce a novel methodology to quantify this induction period using differential scanning calorimetry (DSC) under both isothermal and dynamic conditions. The resulting kinetic parameters were used to construct the TTT map, which delineates a broad and practical processing window. This map enables precise control of the polymerization process, minimizes the risk of thermal degradation, and supports the efficient integration of acrylic resins into industrial composite manufacturing.
