Propagation mechanism
Mandarin:
链增长机理 (liàn zēng zhǎng jī lǐ)
链增长机理 (liàn zēng zhǎng jī lǐ)
Explanation in English Language (EN):
The propagation mechanism is the series of steps by which monomers add to the active center of a growing polymer chain during polymerization. The specific mechanism depends on the type of polymerization (chain-growth or step-growth) and the nature of the active center (free radical, cation, or anion). Understanding the propagation mechanism is crucial for controlling the rate of polymerization, the molecular weight of the polymer, and the polymer's microstructure.

Explanation in Mandarin (ZH):
链增长机理是聚合过程中单体添加到不断增长的聚合物链的活性中心的一系列步骤。具体机制取决于聚合的类型（链增长或逐步增长）和活性中心的性质（自由基、阳离子或阴离子）。了解链增长机理对于控制聚合速率、聚合物的分子量和聚合物的微观结构至关重要。
