What is the purpose of an inhibitor in polymerization control?

• A. To speed up the polymerization process
• B. To prevent unwanted polymerization
• C. To enhance the chemical's hazard
• D. To stabilize the pressure

Answer: (B)

An inhibitor in polymerization control is specifically designed to prevent unwanted polymerization reactions from occurring. This is crucial in various industrial processes where the uncontrolled polymerization of monomers could lead to hazardous conditions, excessive heat generation, or the formation of unwanted byproducts. By adding an inhibitor, the reaction rate is slowed or halted, allowing for better control over the process and ensuring that polymerization occurs only under desired conditions and at the right time. This is particularly important in applications where precise material properties are required, and where safety and stability are paramount.
