Abstract: The present invention provides a method for producing water-absorbent resin particles which show an excellent water absorption rate and high equilibrium swelling capacity and which have an appropriate particle size to be excellent in handleability, and water-absorbent resin particles obtained by the method. The present invention is a method for producing water-absorbent resin particles by reversed phase suspension polymerization of a water-soluble ethylenically unsaturated monomer, the method including the steps of: (A) first reversed phase suspension polymerization of a water-soluble ethylenically unsaturated monomer in a petroleum hydrocarbon dispersion medium using a water-soluble radical polymerization initiator, in the absence of an internal crosslinking agent and in the presence of a surfactant having an HLB of 8 to 12; (B) intermediate crosslinking reaction by adding an intermediate crosslinking agent; (C) second reversed phase suspension polymerization of a water-soluble ethylenically unsaturated monomer added to the petroleum hydrocarbon dispersion medium containing the surfactant dissolved therein using a water-soluble radical polymerization initiator in the absence of an internal crosslinking agent, thereby producing a water-absorbent resin precursor; and (D) post crosslinking reaction of the water-absorbent resin precursor preliminary adjusted to have a moisture content of 30 to 100% by mass relative to a water-soluble ethylenically unsaturated monomer component in the water-absorbent resin precursor. The present invention provides a method for producing water-absorbent resin particles which show an excellent water absorption rate and high equilibrium swelling capacity and which have an appropriate particle size to be excellent in handleability, and water-absorbent resin ...more ...less

Abstract: A process for separation of a hydrocarbon-containing feed stream can include cooling the hydrocarbon-containing feed stream using an absorption refrigeration cycle to form a cooled feed stream. The cooled feed stream can be subjected to distillation conditions to remove a bottom stream including co-monomer; and an overhead stream including hydrocarbon diluents, olefin monomer, and components selected from H2, N2, O2, CO, CO2, and formaldehyde. The overhead stream can be subjected to distillation conditions adapted to remove a bottom stream including substantially olefin-free hydrocarbon diluents; a side stream including hydrocarbon diluent; and an overhead vapor stream including olefin monomer, diluents, and components selected from H2, N2, O2, CO, CO2, and formaldehyde. The overhead vapor stream can be cooled using an absorption refrigeration cycle to form a cooled overhead vapor stream. Olefin monomers can be separated from diluents in the cooled overhead vapor stream.

Abstract: To provide a method for producing an aqueous liquid containing a vinyl polymer, of which the production efficiency is high, without lowering the yield of the vinyl polymer. When removing a hydrophilic organic solvent from a mixed liquid comprising a vinyl polymer, the hydrophilic organic solvent and water to produce an aqueous liquid containing the vinyl polymer, a liquid phase and a gas phase are formed in a closed container, a part of the liquid of the liquid phase is formed into small droplets and brought into contact with the gas phase to vaporize the hydrophilic organic solvent, and the vaporized hydrophilic organic solvent is removed from the closed container. Specifically, for example, a closed container 10 having a liquid inlet 22, a gas outlet 30, a liquid outlet 21, a liquid inlet 22 and a liquid outlet 21 which are connected and having an external circulating system provided with means to control the temperature and the pressure of liquid, is filled with a mixed liquid 40 to form a liquid phase 50 and a gas phase 51, the mixed liquid 40 of the liquid phase 50 is circulated from the liquid outlet 21 to the external circulating system 20, and the temperature and the pressure of the mixed liquid 41 in the external circulating system 20 are controlled to conditions such that the hydrophilic organic solvent is easily vaporized in liquid droplets in the gas phase 51, followed by discharging the mixed liquid 41 in the form of the small droplets from the liquid inlet 22 to the gas phase 51 and draining the gas in the gas phase 51 from the gas outlet 30.
