一般描述
丙烯腈常用作单体，属于不饱和腈类。它可用作生产具有良好性质的各种聚合物和共聚物的关键单体。丙烯腈常用于生产丙烯酸纤维，这种纤维以柔软性、强度和良好的耐热性和耐化学品性而著称。丙烯腈的主要应用领域之一是丙烯腈-丁二烯-苯乙烯（ABS）共聚物的制造。ABS是一种耐用的多功能塑料，广泛应用于汽车部件、设备、电器外壳和消费品。丙烯腈的加入提高了共聚物的耐热性和冲击强度，从而使ABS成为一种备受青睐的材料。
应用
丙烯腈可用于制造丙烯酸纤维、树脂(丙烯腈-丁二烯-苯乙烯、苯乙烯-丙烯腈等)以及丁腈橡胶(丁二烯-丙烯腈)。
丙烯腈可用作单体：
- 用于制备3D打印聚合物材料丙烯腈-丁二烯-苯乙烯（ABS），其是一种常用的工程热塑性塑料，以高强度、耐用性和耐热性而著称。它可用作各种应用（包括医学领域、相容的制造过程、注射成型、吹塑成型和挤出）中的合适基质。
- 与木素磺酸盐共聚以开发碳纤维前体。该共聚物可用作前体材料，经过进一步的热处理后可生成碳纤维。
- 用于合成丙烯酰胺接枝丙烯腈共聚物膜，该共聚物膜可用作细胞酶固定的支撑基质（support matrix ）。
生化/生理作用
属工业致癌物，对大鼠具有多位点致癌性，也可能对人体具有致癌性。
