摘要：
Disclosed herein is a method of preparing an EP(D)M elastomer, which includes pre-cooling a reactive solvent to −80 to −100° C.; and polymerizing ethylene, at least one higher α-olefin having 3 to 18 carbons, and selectively, at least one conjugated or non-conjugated diene having 5 to 15 carbons, in the presence of the reactive solvent. According to the method of the current invention, the yield of the EP(D)M elastomer is drastically increased even though a conventional preparation device is used unchanged. Further, methods of controlling the yield of the EP(D)M elastomer and of recovering the EP(D)M elastomer are provided.
摘要（中）：
本文公开了制备EP（D）M弹性体的方法，其包括将反应性溶剂预冷至-80至-100℃; 并在反应性溶剂的存在下使乙烯，至少一种具有3至18个碳原子的高级α-烯烃和选择性地至少一种具有5至15个碳原子的共轭或非共轭二烯聚合。 根据本发明的方法，即使使用常规的制备装置不变，EP（D）M弹性体的收率也急剧增加。 此外，提供了控制EP（D）M弹性体的收率和回收EP（D）M弹性体的方法。
