专利号:US-7833926-B2 优先权日:2005-07-01 标题 :Arylphenoxy catalyst system for producing ethylene homopolymer or copolymers of ethylene and α-olefins 发明人:WOO TAE WOO; OK MYUNG AHN; HAHN JONG SOK; LEE MAL-OU; KANG SANG OOK; KO SUNG-BO; KIM TAE-JIN; KIM SUNG-KWAN 权利人:SK ENERGY CO LTD 摘要:The present invention relates to an arylphenoxy catalyst system producing an ethylene homopolymer or copolymers of ethylene and α-olefins, and a method of producing an ethylene homopolymer or copolymers of ethylene and α-olefins having a high molecular weight under a high temperature solution polymerization condition using the same. The catalyst system includes a group IV arylphenoxy-based transition metal catalyst and an aluminoxane cocatalyst or a boron compound cocatalyst. In the transition metal catalyst, a cyclopentadiene derivative and arylphenoxide as fixed ligands are located around the group IV transition metal, arylphenoxide is substituted with at least one aryl derivative and is located at the ortho position thereof, and the ligands are not crosslinked to each other. The catalyst includes an environmentally-friendly raw material, synthesis of the catalyst is economical, and thermal stability of the catalyst is excellent. It is useful for producing an ethylene homopolymer or copolymers of ethylene and α-olefins having various physical properties in commercial polymerization processes.
专利号:WO-9729091-A1 优先权日:1996-02-09 标题:Balanol analogues 发明人:NIELSEN JOHN; LYNGSOE LARS OLE 权利人:AUDA PHARMACEUTICALS APS; NIELSEN JOHN; LYNGSOE LARS OLE 摘要:The present invention relates to a solid phase methodology for the preparation of a combinatorial library of structural analogues of the natural product balanol (ophiocordin, azepinostatin), which is a protein kinase C (PKC) and protein kinase A (PKA) inhibitor. The method comprises solid-phase synthesis of the analog variants of balanol whereby a high molecular diversity is introduced. The synthetic scheme is based on a retrosynthetic analysis of the native structure which revealed three main building blocks suitable as templates for modification. The dicarboxy-functional moiety can be immobilised to the polymer support either as the monoallyl ester or as the internal anhydride. The libraries produced by the method are especially suited for high throughput screening of potential drug candidates for the treatment of mammals, especially humans.
