Adiabatic polymerization is a process of polymerizing monomers without any external heat or cooling. During the polymerization reaction, heat is generated due to the exothermic nature of the reaction, which can cause the temperature to rise rapidly. In adiabatic polymerization, the heat generated is not allowed to dissipate to the surroundings, resulting in an increase in the reaction temperature. The high reaction temperature can lead to issues such as thermal runaway, which can cause the reaction to become uncontrollable and result in a hazardous situation. To prevent this, proper reactor design, process control, and safety measures are essential. Adiabatic polymerization is commonly used in the production of various types of polymers, including thermosetting resins and polyurethanes.
