中文摘要 | EPDM為乙烯/丙烯之共聚物或乙烯/丙烯/二烯之三聚物,加入二烯(diene)的好處 在於可在產物的側鏈保留不飽和雙鍵,以便在後段加工時,再以較經濟的加硫艾聯方法,尤 其在射出及押出成形時, 此種快速交聯的特性更具競爭力。 EPDM 的商用觸媒為釩或鈦的 Ziegler-Natta 觸媒,但各有其缺點,以 Metallocene 技術生產 EPDM,除了產品性質好, 分子量可控制等優點外,更可降低生產成本極具競爭力。本文即簡單介紹 EPDM 的現有生產 技術,並探討以 Metallocene 觸媒技術在 EPDM 應用的最新發展。 |
英文摘要 | Recent application of metallocene technology in EPDM production poses many advantages over the conventional Ziegler-Natta catalysts, such as much higher activities, random comonomer distribution, narrow MWD, tailorable MW, and high comonomer incorporation rate. Moreover, it is estimated that mamufacturing EPDM by metallocene technology can lower the production cost and make the process more competible. This article brief by reviewing key factors in EPDM production and recent development of metallocene technology in this area. |
