摘要： Provided are a composition for forming an absorption-desorption sheet, an absorption-desorption sheet including the same, and a method of preparing the absorption-desorption sheet. The composition for forming an absorption-desorption sheet includes: a polymerizable first monomer or oligmer comprising an ionic hydrophilic group; a polymerizable second monomer or oligmer comprising a non-ionic hydrophilic group; and a deliquescent salt that has excellent absorption-desorption performance- and allows repeated use of the absorption-desorption sheet. In addition, the absorption-desorption sheet has antibacterial and deodorant performance, and thus, is able to inhibit the growth of bacteria and fungi in a humid environment.

摘要： Temperature-responsive poly(2-hydroxyethyl methacrylate) (PHEMA) and a preparation method thereof are disclosed. In the preparation method, with a system consisting of benzoyl peroxide (BPO) (an oxidant) and 2-methyl-N-[3-(methyl-phenyl-amino)-propyl]-acrylamide (MPAEMA) or 2-methyl-N-[3-(methyl-phenyl-amino)-propyl]-propionamide (MEMA) (a reducing agent monomer) as a redox initiation system, water and toluene as media, a nonionic surfactant as an emulsifier, and 2-hydroxyethyl methacrylate (HEMA) as a polymerization monomer, polymerization is conducted at room temperature and atmospheric pressure to obtain the PHEMA. An alcohol solution of the PHEMA has an upper critical solution temperature (UCST). The method has the advantages of simple and stable polymerization system, low polymerization cost, easy operation, mild conditions, small impact on the environment, and low energy consumption. Moreover, a molecular weight and UCST of a product are controllable within a specified range.

摘要： A continuous inverse emulsion polymerization process may involve combining an aqueous monomer composition with an oil composition in a premix vessel and allowing the aqueous monomer composition to interact with the oil composition in the premix vessel for a period of time effective to form a stable pre-emulsion. The stable pre-emulsion may then be homogenized to form a homogenized emulsion that is then polymerized to form a water-in-oil inverse emulsion polymer. By forming a stable pre-emulsion that is then homogenized, the resulting water-in-oil inverse emulsion polymer may have uniform and consistent polymer size distribution.

摘要： Provided herein is a cationic polymer obtainable by polymerization of at least one cationic monomer, at least one crosslinker and optionally further monomers, such as nonionic monomers, associative monomers, and/or chain transfer agents. The cationic polymer has an at least bimodal molecular weight distribution with at least one first peak (P1) and at least one second peak (P2), wherein the first peak has a rather low average sedimentation coefficient of ≤10 Sved and the second peak has a rather high average sedimentation coefficient of ≥10,000 Sved. The water-soluble polymer components of the cationic polymer are ≥25% by weight related to the total amount of cationic polymer. Further provided herein is a process for obtaining such a cationic polymer as well as to an inverse dispersion, a thickener or a deposition aid, including at least one of such cationic polymers.

摘要： The present invention generally relates to methods for resolving water and oil emulsions in the produced fluid of an oil production system comprising adding a structured copolymer reverse emulsion breaker to the produced fluid of the crude oil production system in an amount effective for resolving an oil-in-water emulsion. In particular, these methods for resolving an oil-in-water emulsion can be used in separation processes where the oil and solids in the produced fluid are separated from the produced water in the produced fluid.
