    摘要: In a process for producing an elongated polyethylene component, such as a fiber or membrane, polyethylene powder having a molecular weight of at least 3 x 105 g/mol as determined by ASTM 4020 is dissolved in a solvent to produce an extrudable solution. The solution is then extruded through a die to form an elongated component and at least part of said solvent is removed from the elongated component. The polyethylene powder used in the process is produced by polymerizing ethylene in the presence of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand.

    摘要: In a process for producing polyethylene having a molecular weight of at least 3 x 105 g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition in at least one hydrocarbon. The catalyst composition comprises a Group 4 metal complex of a phenolate ether ligand and the slurry includes from about 5 to less than 40 ppm per liter of a compound effective to increase the conductivity of said at least one hydrocarbon.

    摘要: Derivatives of amino-benzoic acids, hydroxy-benzoic acids, cinnamic acids, urocanic acids and benzimidazols have been synthetized. The photoprotector power of each class of compounds has been tested. It is the result of four different isolated or conjugate mechanisms. Mechanism 1: absorption of ultraviolet radiations between 360 nm and 260 nm (UVB and/or UVA). Mechanism 2: prolonged absorption of ultraviolet radiations between 360 nm and 260 nm by preferential fixation and in a prolonged way at the epiderm of the human skin of the compound and this by introducing into their chemical structure sulphured or not, peptidic, amino-acid groups. Mechanism 3: induction of the melanogenesis, natural protection system of the skin. Mechanism 4: selection of a compound which is either liposoluble or hydrosoluble according to the galenic form (solution, emulsion, spray). The present invention claims the chemical structure of new compounds, their synthesis, photoprotective activity and the utilization of all the disclosed compounds in order to avoid photodermatosis consecutive to the administration of medicaments, to the use of cosmetics and/or perfumes by man.

    摘要: In a process for producing polyethylene, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition comprising a particulate support and a Group 4 metal complex of a phenolate ether ligand carried by the support and present in an amount so as to provide about 0.1 to about 35 μιηοΐ of Group 4 metal per gram of the support. The resultant polyethylene has a molecular weight of at least 3 x 105 g/mol as determined by ASTM 4020, an average particle size, d50, of less 300 microns, preferably about 100 to 250 microns, and a span, log 10 (d 90 /d 10 ), of less than 0.4.
