Technical Field

[0002] Inhibitor is an industrial auxiliary agent, usually used to prevent the polymerization. Inhibitor molecules react with chain free radicals to form non-free radical substances or low-activity free radicals that cannot be triggered, thereby terminating the polymerization. In order to prevent olefin monomers from polymerizing during storage and transportation, a small amount of inhibitor is often added to the monomer and removed before use. The selection of inhibitors mainly requires high inhibition efficiency. Its solubility in the monomer and its adaptability to the monomer should also be considered. The inhibitor should be easily removed from the monomer by distillation or chemical methods. It is best to select an inhibitor that can inhibit polymerization at room temperature and can quickly decompose at the reaction temperature. This way, it does not need to be removed from the monomer, reducing trouble and ensuring the smooth progress of the polymerization reaction.
