Tacticity
Mandarin:
立构规整度 (lì gòu guī zhěng dù)
立构规整度 (lì gòu guī zhěng dù)
Explanation in English Language (EN):
Tacticity describes the relative stereochemistry of adjacent chiral centers in a polymer chain. It refers to the arrangement of substituents along the polymer backbone. There are three main types of tacticity: isotactic (all substituents on the same side), syndiotactic (substituents alternate sides), and atactic (random arrangement of substituents). Tacticity significantly influences the physical properties of polymers, such as their crystallinity, melting point, and mechanical properties.

Explanation in Mandarin (ZH):
立构规整度描述了聚合物链中相邻手性中心的相对立体化学。它是指取代基沿聚合物主链的排列。立构规整度主要有三种类型：全同立构（所有取代基都在同一侧）、间同立构（取代基交替排列）和无规立构（取代基随机排列）。立构规整度会显着影响聚合物的物理性质，例如其结晶度、熔点和机械性能。
