Free radical polymerization
Mandarin:
自由基聚合 (zì yóu jī jù hé)
自由基聚合 (zì yóu jī jù hé)
Explanation in English Language (EN):
Free radical polymerization is a common chain-growth polymerization mechanism that involves free radicals as the active centers. The process typically consists of three main steps: initiation, propagation, and termination. Initiation involves the generation of free radicals, often through the decomposition of an initiator. These radicals then react with monomers to start the growing chain. Propagation involves the addition of more monomers to the growing chain. Termination occurs when two growing chains react with each other, ending the polymerization process. Free radical polymerization is used to produce a wide variety of polymers, including polyethylene, polystyrene, and PVC.

Explanation in Mandarin (ZH):
自由基聚合是一种常见的链增长聚合机理，涉及自由基作为活性中心。该过程通常包括三个主要步骤：引发、增长和终止。引发涉及自由基的产生，通常通过引发剂的分解来实现。然后这些自由基与单体反应以开始不断增长的链。增长涉及向不断增长的链中添加更多单体。当两条不断增长的链相互反应时，就会发生终止，从而结束聚合过程。自由基聚合用于生产各种聚合物，包括聚乙烯、聚苯乙烯和 PVC。
