Steric hindrance
Mandarin:
位阻 (wèi zǔ)
位阻 (wèi zǔ)
Explanation in English Language (EN):
Steric hindrance refers to the effect of bulky groups or atoms on the rate or outcome of a chemical reaction. When bulky groups are present around a reactive site, they can hinder the approach of other molecules, slowing down the reaction or preventing it altogether. Steric hindrance is an important consideration in polymer chemistry, as it can affect the reactivity of monomers, the rate of polymerization, and the conformation and properties of polymers.

Explanation in Mandarin (ZH):
位阻是指庞大的基团或原子对化学反应速率或结果的影响。当反应位点周围存在庞大的基团时，它们会阻碍其他分子的接近，从而减缓反应速度或完全阻止反应。位阻是高分子化学中的一个重要考虑因素，因为它会影响单体的反应性、聚合速率以及聚合物的构象和性质。
