    • Disclosed is a secondary battery comprising a cathode, an anode, a separator and an electrolyte, wherein the electrolyte comprises a eutectic mixture formed of: (a) an amide group-containing compound, and (b) an ionizable lithium salt, and the anode comprises a metal or metal oxide having a potential vs. lithium potential (Li/Li+) within electrochemical window of the eutectic mixture. An electrolyte for a secondary battery comprising the eutectic mixture is also disclosed. Since the secondary battery uses a eutectic mixture as an electrolyte in combination with an anode having a potential vs. lithium potential (Li/Li+) within the electrochemical window of the eutectic mixture, it solves the problems occurring in a conventional battery using a eutectic mixture as an electrolyte, such problems including decomposition of an electrolyte and degradation of the quality of a battery. Also, due to the thermal and chemical stability, high conductivity and a broad electrochemical window of a eutectic mixture, it is possible to improve the quality as well as safety of a battery.

    • The present invention relates to a metallocene compound and the olefin polymerization using the same, particularly to a metallocene compound and the olefin polymerization using this compound on which supported catalysts are easily prepared by the reaction of the ligand containing —(CR12)a—O—SiRbYc ligand (wherein each Y, which can be the same as or different from other Y, is a hydrogen, halogen, alkoxy, aryloxy, amide, or silyloxy radical, each R1, which can be the same as or different from other R1, is a hydrogen radical, or an alkyl, cycloalkyl, aryl, alkenyl, alkylaryl, arylalkyl, or arylalkenyl radical having from 1 to 40 carbon atoms, each R, which can be the same as or different from other R, is an alkyl, cycloalkyl, aryl, alkenyl, alkylaryl, arylalkyl, or arylalkenyl radical having from 1 to 40 carbon atoms, a is an integral number from 1 to 40, c is 1, 2, or 3, and the sum of b and c is 3) with a support. Furthermore, the present invention relates to a supported metallocene catalyst using this metallocene compound and the olefin polymerization using the same. The metallocene compounds in this invention have superior characteristics in the preparation of supported catalyst due to the high reactivity with the support and minimal side reactions during the anchoring process. In addition, the olefin polymerization process employing the supported catalyst in this invention proceeds without fouling in the reactor, and the morphology and bulk density of the polymer produced are better than that produced by the conventional method.

    • Disclosed are catalyst preparation olefin polymerization processes with the recycling of a co-catalyst. According to the olefin polymerization process activated single-site catalysts are prepared by contacting supported single-site pre-catalyst with an organic solvent containing co-catalyst. The activated single-site catalysts are separated from co-catalysts dissolved in an organic solvent and the olefin polymerization is conducted using the separated single-site catalysts with one or more olefinic monomers. The separated co-catalysts is reused by recycling the organic solvent containing the separated co-catalysts and contacting them with the supported single-site pre-catalysts. The olefin polymerization process of the present invention enables recycling expensive co-catalyst for subsequent olefin polymerization and accordingly the total amount of co-catalyst required can be significantly reduced.
    • 公开了催化剂制备烯烃聚合方法与助催化剂的再循环。 根据烯烃聚合方法,活化的单中心催化剂是通过将负载的单部位预催化剂与含有助催化剂的有机溶剂接触来制备的。 将活化的单中心催化剂与溶于有机溶剂中的助催化剂分离,并使用分离的单中心催化剂与一种或多种烯属单体进行烯烃聚合。 分离的助催化剂通过再循环含有分离的助催化剂的有机溶剂并将其与负载的单位点预催化剂接触来再利用。 本发明的烯烃聚合方法使得可以再循环昂贵的助催化剂用于随后的烯烃聚合,因此可显着降低所需的助催化剂的总量。
