  • Patent number: 9976001
    Abstract: Provided is a process for producing a water-absorbing resin powder which contains a given amount of water added thereto, has a low dust content, and has high material properties. When a water-absorbing resin powder which has undergone surface crosslinking is produced on an industrial scale, various problems concerning production are eliminated and a long-term stable operation is possible without causing a deterioration in the material properties of the resin. Even when the process is continued over a long period, the material properties are stabilized (decrease in standard deviation) or improved (improvement in AAP). The process for producing a water-absorbing resin comprises, in the following order, a first classification step for classifying a water-absorbing resin, a surface crosslinking step after the classification, a water addition step for adding water to the water-absorbing resin powder after or during the surface crosslinking, a second classification step, and a conveying step.

  • Patent number: 8816003
    Abstract: This invention involves a composition, a method of making, and an application of high plasticization-resistant chemically cross-linked polymeric membranes such as cross-linked cellulose acetate (CA) membrane. These cross-linked polymeric membranes with covalently interpolymer-chain-connected rigid networks showed no decrease in CO2/CH4 ideal selectivity under 690 kPa (100 psig) pure CO2 pressure and also no CO2 plasticization up to 3447 kPa (500 psig) pure CO2 pressure. By using the method of chemical cross-linking as described in this invention, the separation characteristics of the polymeric membranes can be decisively improved. These new cross-linked polymeric membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as pervaporation and desalination.

  • Patent number: 8323838
    Abstract: The invention described the highly conducting amorphous polymer materials which are based on the pure block-type copolymers, which contain polyethylene oxide and other chemically complementary blocks and form the amorphous hydrogen-bonded intramolecular polycomplexes, and those, filled by ion conductive materials, low-molecular-weight organic plasticizer and nanometer-scale inorganic particles. The block-type copolymers are preferably the linear triblock copolymers with a central block of PEO and two side blocks of chemically complementary polyacrylamide (PAAm) or poly(acrylic acid) (PAAc). Due to existence of long side PAAm chains and their interaction with a central crystallizable block of PEO, TBC bulk structure is amorphous and fully homogeneous. It can be represented as a totality of hydrogen-bonded segments of both polymer components, uniformly distributed in PAAm matrix. Presented polymer materials can be used for solid polymer electrolyte for DSSC solar cells and lithium batteries.
