又稱為嵌段共聚合物。因單聚合物本身脆性高，為大幅改善耐衝擊性，故在聚合過程中將乙烯丙烯橡膠(EPR)生成分佈於單聚合物中。耐衝擊共聚物除了在常溫下擁有良好的耐衝擊性，在低溫下仍保有不錯的耐衝擊性，更適合在低溫下使用。除此之外，耐衝擊共聚合物還具有優良的長期熱安定性(耐老化性)，使其在汽機車與家電上的應用更加廣泛。
Also known as block copolymers. Due to the high brittleness of the single polymer itself, in order to significantly improve its impact resistance, ethylene propylene rubber (EPR) is generated and distributed in the single polymer during the polymerization process. Impact resistant copolymers not only have good impact resistance at room temperature, but also maintain good impact resistance at low temperatures, making them more suitable for use at low temperatures. In addition, impact resistant copolymers also have excellent long-term thermal stability (aging resistance), making their applications in steam turbines, vehicles, and household appliances more widespread.
