Chain transfer
Mandarin:
链转移 (liàn zhuǎn yí)
链转移 (liàn zhuǎn yí)
Explanation in English Language (EN):
Chain transfer is a key step in chain-growth polymerization that involves the transfer of the active center (radical, cation, or anion) from a growing polymer chain to another molecule. This terminates the growth of the original chain and initiates a new chain. Chain transfer can occur with various species, including monomers, solvents, initiators, or chain transfer agents. It is often used to control the molecular weight and molecular weight distribution of polymers.

Explanation in Mandarin (ZH):
链转移是链增长聚合中的一个关键步骤，涉及将活性中心（自由基、阳离子或阴离子）从不断增长的聚合物链转移到另一个分子。这终止了原始链的增长并引发了新链。链转移可以发生在各种物质上，包括单体、溶剂、引发剂或链转移剂。它通常用于控制聚合物的分子量和分子量分布。
