摘要： Provided is a method of preparing styrene polymers, the method comprising: homogeneously mixing a styrene monomer; a cocatalyst mixture of Group 13 metal-containing organic metal compound cocatalyst and an inert organic solvent; and a catalyst mixture of a metallocene catalyst and the inert organic solvent using a high speed homogenizing mixer to obtain a homogenized mixture; and providing the homogenized mixture to a reactor to initiate polymerization. In this method, catalyst is quickly dispersed among monomers using a high speed homogenizing mixer so that formation of gel, which occurs when a syndiotactic styrene polymer is produced, can be fundamentally prevented. In addition, a styrene polymer prepared using the method has high activity, good stereoregularity, and uniform molecular distribution.

摘要： The present invention relates to a method for producing (meth)acrylic acid comprising a process of recovering (meth)acrylic acid as an aqueous (meth)acrylic acid from a (meth)acrylic acid-containing gas mixture produced by the catalytic gas phase oxidation of at least one reactant selected from the group consisting of propane, propylene, isobutylene and (meth)acrolein, and a system usable for the method. The recovery process comprises the steps of: (1) feeding the (meth)acrylic acid-containing gas mixture into a quenching tower and condensing it in the quenching tower so as to recover an aqueous (meth)acrylic acid solution from the bottom of the quenching tower, in which some of the recovered aqueous solution of (meth)acrylic acid is recycled to the top part of the quenching tower so as to condense the (meth)acrylic acid-containing gas mixture; (2) passing the uncondensed part of the (meth)acrylic acid-containing gas mixture from the quenching tower through the top of the quenching tower to an absorption column; (3) absorbing (meth)acrylic acid contained in the uncondensed part of the (meth)acrylic acid-containing gas mixture in the absorption column with a absorption solvent; (4) feeding the (meth)acrylic acid solution resulting from the absorption in the step (3) to a desorption column; and (5) separating the solvent used in the step (3) from the (meth)acrylic acid solution in the desorption column, so that the substance from which the solvent has been removed in the desorption column is fed to the quenching tower, and the separated solvent is recycled to the absorption column. The inventive method is an efficient and economic method which allows a reduction in energy consumption in subsequent purification processes by maximizing the concentration of an aqueous solution of (meth)acrylic solution recovered at the bottom of the quenching tower and minimizing the concentration of (meth)acrylic acid lost from the vent gas of the absorption column.

摘要： An LCD device has scratch-resistant property without using a protection sheet and can provide enhanced brightness. The LCD device includes a light path regulating member. The member includes a first prism sheet having first prisms of which apex has a round shape. The first prism sheet concentrates light supplied from a lamp to output the concentrated light. An anti-glare polarizing plate uniformly polarizes polarized planes of the concentrated light and provides the polarized light to the lower substrate. The anti-glare polarizing plate is arranged below the lower substrate of an LCD panel, and an uppermost prism sheet of optical sheets is non-matte-treated and has round-treated apexes. In spite of the absence of the protection sheet, the scratch-resistant property of the uppermost prism sheet and the brightness of the LCD panel may be enhanced.

LPK7) having disruptions of a lactate dehydrogenase gene (ldhA), a pyruvate formate-lyase gene (pfl), a phosphotransacetylase gene (pta), and a acetate kinase gene (ackA); a novel bacterial mutant (Mannheimia sp. LPK4) having disruptions of a lactate dehydrogenase gene (ldhA), a pyruvate formate-lyase gene (pfl) and a phosphoenolpyruvate carboxylase gene (ppc) involved in the immobilization of CO2 in a metabolic pathway of producing succinic acid; and a method for producing succinic acid, which is characterized by the culture of the above mutants in anaerobic conditions. The inventive bacterial mutants have the property of producing succinic acid at high concentration while producing little or no organic acids, as compared to the prior wild-type strains of producing various organic acids. Thus, the inventive bacterial mutants are useful as strains for the industrial production of succinic acid.

摘要： Disclosed is a diamond tool having a metal plate inserted therein. Between abrasive layers containing diamond particles is inserted a ferrous or non-ferrous metal plate having a wear resistance lower than that of the abrasive layers such that a concave groove is spontaneously formed during a cutting process, thereby reducing the contact load with a workpiece to thereby avoid vibration (wobbling) of a shank, and providing a discharge path for smoothly removing cutting chips and the cooling water. In addition, the content of abrasives and the wear resistance of bonding material are uniformly constituted so that the shrinkage rate does not need to be considered during sintering and the manufacturing process can be simplified, thereby reducing the manufacturing cost and improving the productivity therefor. Furthermore, the area of the metal plate can be controlled, thereby enabling an easy design conforming to the working conditions with a workpiece.

摘要： A backlight assembly and a liquid crystal display device can discharge heat from the lamp unit to the outside or effectively dissipate the heat. The backlight assembly of the present invention includes a lamp unit, a receiving member for receiving the lamp unit, a first heat dissipation member disposed below the receiving member, and a second heat dissipation for wrapping around a lateral side of the receiving member and the first heat dissipation member. The lamp unit is disposed on an area corresponding to the lateral side of the receiving member. In one embodiment, the first heat dissipation member is a flat plate made of graphite and disposed on an outer side of the bottom of the receiving member. The second heat dissipation member is metal with good thermal conductivity in close contact with the first heat dissipation member and the lateral side of the receiving member where the lamp unit is disposed. Thus, the heat discharged from the lamp unit can be distributed uniformly over the entire area of the receiving member. In addition, the lateral side of the receiving member where the lamp unit is disposed can be replaced with the second heat dissipation member.
