  • Patent number: 9624322
    Abstract: A method for producing a water absorbent resin, the method including a polymerization step, a drying step, a classification step, and a surface crosslinking step. The classification step carried out before or after the surface crosslinking step requires use of a tapping material and a metal sieve mesh, in which the tapping material being heated at 40° C. to 100° C. is installed below the metal sieve mesh, and the metal sieve mesh has an area of 1 to 10 m2/sheet. The classification step further requires introducing a classification aid particle, which has a specific gravity different from that of the water absorbent resin, to the metal sieve mesh; and monitoring the presence or absence of damage to the metal sieve mesh.

  • Patent number: 8492481
    Abstract: The present invention relates to a block polymeric material. Typically the block polymer comprises units capable of having an average cationic charge density of about 15 or less, preferably 5 or less, more preferably from about 0.05 to about 5, even more preferably from about 0.05 to about 2.77, even more preferably from about 0.1 to about 2.75, most preferably from about 0.75 to about 2.25 units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for personal care products such as soaps and shampoos. The compositions have increased effectiveness for preventing re-deposition of grease during hand and body washing. The polymers are also effective as a soil release agent in fabric cleaning compositions.
