不饱和聚酯树脂（Unsaturated Polyester Resin，简称UPR）是一种热固性高分子化合物，主要由不饱和二元酸（如马来酸酐）与二元醇（如乙二醇）缩聚反应生成，并加入乙烯基单体（如苯乙烯）作为交联剂。
化学结构
分子主链含重复的酯键和不饱和双键，通过缩聚反应形成线型聚合物。不饱和双键赋予其高反应活性，可与交联剂发生自由基共聚反应，形成三维网状结构。
固化过程
在引发剂（如过氧化物）作用下，双键与乙烯基单体交联，形成不溶不熔的固体。固化时伴随收缩，收缩率较大，需通过填料或工艺优化改善。
物理性质
主要用于复合材料（如玻璃钢）、涂层、人造石材、汽车零部件及电子封装材料。其液态特性便于涂覆和成型，固化后机械强度高。
