巴陵石化万吨级SEPS成套技术开发项目列入中石化攻关计划

氢化苯乙烯/异戊二烯共聚物（SEPS）是以苯乙烯、异戊二烯为单体，以烷基锂为引发剂聚合得到共聚物，然后再对共聚物中的异戊二烯链节双键选择性催化加氢(苯乙烯链节不加氢)而得到的产品。尽管SEPS在高端领域应用广泛，但受其选择加氢工艺技术复杂、加氢后聚合物中金属离子脱除难度大等影响，目前全球只有美国科腾公司和日本可乐丽公司实现了工业化，并垄断全球市场，其价格比普通SEBS产品高数万元。

中国石化科技攻关领导小组要求巴陵石化加快SEPS新产品、新牌号开发，加速工业装置建设和工业试验，大力开展SEPS 产品应用及推广，届时，巴陵石化“氢化苯乙烯/异戊二烯共聚物成套技术”产业化将填补国内空白，促进锂系聚合物高端产品开发与应用，实现产品升级换代，争创良好经济和社会效益。

Hydrogenated styrene / isoprene copolymer (SEPS) based on styrene , isoprene as monomer , an alkyl lithium as a polymerization initiator to obtain a copolymer , then the chain of the copolymer of isoprene double selective catalytic hydrogenation section ( not hydrogenated styrene mer ) obtained products. Although SEPS widely used in high-end, but by its selective hydrogenation technology complex , hydrogenated polymers difficult to remove metal ions such as impact of the current global Kraton only the United States and Japan Kuraray Company achieved industrialization and dominate the global market , its price is higher than the average SEBS products several million.
