Chain-growth polymerization
Mandarin:
链式增长聚合 (liàn shì zēng zhǎng jù hé)
链式增长聚合 (liàn shì zēng zhǎng jù hé)
Explanation in English Language (EN):
Chain-growth polymerization is a major polymerization mechanism where monomers add to the active center of a growing polymer chain one at a time. This process typically involves three distinct steps: initiation, propagation, and termination. Chain-growth polymerization is widely used to produce a variety of polymers, including polyethylene, polypropylene, polystyrene, and PVC. This mechanism is particularly effective for vinyl monomers and diene monomers. The key feature is the presence of a reactive center at the end of the growing chain, which can be a free radical, a cation, or an anion.

Explanation in Mandarin (ZH):
链式增长聚合是一种主要的聚合机理，其特征在于单体添加到不断增长的聚合物链的活性中心。该过程通常包括三个不同的步骤：引发、增长和终止。链式增长聚合广泛用于生产各种聚合物，包括聚乙烯、聚丙烯、聚苯乙烯和 PVC。该机理对乙烯基单体和二烯单体特别有效。关键特征是在生长链的末端存在一个反应中心，它可以是自由基、阳离子或阴离子。
