Ammonium Persulfate Initiator for Free Radical Polymerization


Ⅰ How Ammonium Persulfate Initiates Free Radical Polymerization

(1) Core Process: Self-decomposition of Ammonium Persulfate

Featuring a stable chemical structure, ammonium persulfate remains inert under normal conditions and tends to decompose only under specific circumstances. This reaction can be triggered by simple external conditions without extra complex additives, breaking its stable structure to generate highly active chemical groups. Characterized by mildness and controllability, its self-decomposition produces no harmful by-products, laying a pure and stable foundation for subsequent polymerization and serving as the primary step of the whole free radical polymerization process.

(2) Polymerization Initiation: Chain Reaction of Free Radicals

The active groups decomposed from ammonium persulfate are free radicals. With extremely high reactivity, free radicals actively interact with polymerization monomers to break their stable structure and bond monomer molecules together. The reaction proceeds in a chain mode. After one free radical initiates the reaction of a monomer, it transfers onto the monomer to form a new free radical center and extend molecular chains continuously. New free radicals further trigger reactions of other monomers in cycles, connecting monomers into long-chain structures and completing the polymerization process step by step. The whole chain reaction proceeds orderly and efficiently to sustain the polymerization reaction and finally form complete high-molecular polymers.

(3) Core Advantages: Reasons for Choosing Ammonium Persulfate

Ammonium persulfate gains wide popularity among various free radical polymerization initiators thanks to multiple prominent merits. Firstly, it has excellent stability and is resistant to decomposition during storage and transportation, facilitating daily management and operation. Secondly, it delivers high initiation efficiency to start polymerization rapidly with easy-to-control reaction progress, effectively avoiding excessive violent reaction or incomplete reaction. Thirdly, it enjoys great compatibility with various polymerization monomers and is applicable to diverse free radical polymerization reactions with wide coverage. In addition, it allows convenient post-treatment and causes no adverse impacts on the performance of polymerized products, ensuring stable quality of finished goods.
