Carothers equation
Mandarin:
卡罗瑟斯方程 (kǎ luó sè sī fāng chéng)
卡罗瑟斯方程 (kǎ luó sè sī fāng chéng)
Explanation in English Language (EN):
The Carothers equation is a fundamental concept in step-growth polymerization. It establishes a mathematical relationship between the degree of polymerization (DP) and the extent of reaction (p). The equation is expressed as DP = 1/(1-p), where DP represents the average number of monomer units in a polymer chain, and p is the fraction of functional groups that have reacted. This equation helps predict the average molecular weight of the polymer based on how far the reaction has progressed. It's particularly useful in understanding how reaction conditions, like stoichiometric balance of monomers, influence the final molecular weight of the polymer.

Explanation in Mandarin (ZH):
卡罗瑟斯方程是逐步增长聚合中的一个基本概念。它建立了聚合度 (DP) 和反应程度 (p) 之间的数学关系。该方程表示为 DP = 1/(1-p)，其中 DP 表示聚合物链中单体单元的平均数，p 是已反应的官能团的分数。该方程有助于根据反应进行的程度预测聚合物的平均分子量。它对于理解反应条件（如单体的化学计量平衡）如何影响聚合物的最终分子量特别有用。
