Stoichiometry is the calculation of the relative quantities of reactants and products in a chemical reaction. It is based on the balanced chemical equation and the mole concept. In polymerization, stoichiometry is important for determining the amounts of monomers needed to achieve a desired molecular weight and composition of the polymer.

化学计量学是计算化学反应中反应物和产物的相对量。它基于平衡的化学方程式和摩尔概念。在聚合中，化学计量对于确定实现聚合物的所需分子量和组成所需的单体量很重要。
