A comparative study on the effect of various catalysts used in polycarbonate blends

Polycarbonates are a flexible and transparent thermoplastic, have become indispensable in our everyday lives due to its outstanding qualities. This introduction sets the ground for an investigation of catalytic improvements in polycarbonate blends by highlighting their distinctive qualities, benefits over materials like polymethyl methacrylate (PMMA), and compatibility with other polymers. With exceptional physical and chemical properties, polycarbonates outperform PMMA in terms of heat tolerance and impact resistance. When combined with other polymers, they gain even more value, helping sectors like optical media and safety devices. In order to improve polycarbonate blends, speed up processes, and increase material stability, catalysts are essential. In this work, catalytic reactions in polycarbonate blends with PET, PLA, PBT, PMMA, ABS, LCP and PVC are examined. Understanding these systems enables the development of novel materials with the potential to enhance a variety of industries. In the next years, these catalysts are set to bring about profound changes to many leading industries. • Catalytic reactions in polycarbonate blends with PET, PLA, PBT, and PMMA are examined. • The titanium-based catalyst showed the maximum catalytic activity and retained 100 % solubility in PET blends. • PBT/PC blends highlighted the importance of miscibility and processing conditions. • In PC/PMMA blends, the addition of hydrophilic silica nanoparticles leads to deteriorating thermo-mechanical properties.
