Molecular weight
Mandarin:
分子量 (fēn zǐ liàng)
分子量 (fēn zǐ liàng)
Explanation in English Language (EN):
Molecular weight (MW) is the mass of a molecule. In polymer chemistry, it refers to the mass of a polymer chain. Molecular weight is typically expressed in grams per mole (g/mol) or Daltons (Da). The molecular weight of a polymer significantly influences its properties, such as viscosity, melting point, and mechanical strength. Polymers with higher molecular weights tend to have higher strength and viscosity.

Explanation in Mandarin (ZH):
分子量 (MW) 是分子的质量。在高分子化学中，它是指聚合物链的质量。分子量通常以克/摩尔 (g/mol) 或道尔顿 (Da) 表示。聚合物的分子量会显着影响其性能，例如粘度、熔点和机械强度。分子量较高的聚合物往往具有较高的强度和粘度。
