Stereochemistry

Mandarin:
立体化学 (lì tǐ huà xué)
Explanation in English Language (EN):
Stereochemistry is the study of the spatial arrangement of atoms in molecules and its effect on the properties and reactions of those molecules. In polymer chemistry, stereochemistry is particularly important because the arrangement of substituents along a polymer chain can significantly affect the polymer's properties, such as its crystallinity, melting point, and mechanical properties.
Explanation in Mandarin (ZH):
立体化学是研究分子中原子的空间排列及其对这些分子的性质和反应的影响。在高分子化学中,立体化学尤其重要,因为取代基沿聚合物链的排列会显着影响聚合物的性质,例如其结晶度、熔点和机械性能。
