Polymers can have both amorphous and crystalline regions. Amorphous regions are those where the polymer chains lack order and are arranged randomly. These regions contribute to the flexibility and elasticity of a polymer. The proportion of amorphous and crystalline regions significantly influences the overall properties of a polymer.

聚合物可以同时具有无定形区域和结晶区域。无定形区域是聚合物链缺乏有序性并随机排列的区域。这些区域有助于聚合物的柔韧性和弹性。无定形区域和结晶区域的比例显着影响聚合物的整体性能。
