Description

Technical Field

[0001] The invention relates to the technical field of terminator production, in particular to a stable multi-effect reactor for producing environmentally friendly and efficient terminators. Background Art

[0002] Terminator, also known as polymerization stabilizer, is an agent used in the polymer chain polymerization process. It is a substance that can terminate the polymerization reaction in the chain polymerization reaction. These substances can react with initiating free radicals and growing free radicals, making them inactive, thereby terminating the growth of the chain and stopping the polymerization reaction. Its role is a terminator of free radicals. Timely termination of the polymerization reaction can obtain high-quality polymer products with uniform molecular weight and stable molecular structure. In the production, storage and transportation of some polymer monomers, in order to prevent the occurrence of automatic polymerization of monomers, terminators, such as styrene, methacrylic acid and other monomers, need to be added. They act as stabilizers and inhibitors. The terminators need to be processed and mixed in the reactor during the production process. There are many types of terminators, among which the more common ones are acid terminators, alkaline terminators, oxidant terminators and reductant terminators.
