The average kinetic chain length is a measure of the average number of monomer units added per initiating radical before termination occurs in a radical polymerization. It represents the average length of the growing polymer chains before the chain reaction is stopped. This value is influenced by factors like initiator concentration, monomer concentration, and the presence of chain transfer agents.

平均动力学链长是在自由基聚合中终止发生之前每个引发自由基添加的单体单元的平均数量的量度。它表示在链式反应停止之前不断增长的聚合物链的平均长度。该值受引发剂浓度、单体浓度和链转移剂的存在等因素的影响。
