A method for preparing the superabsorbent polymer is also provided.

The present disclosure relates to a method for preparing a super absorbent polymer. More specifically, the above method performs a polymerization reaction of a monomer in the presence of an aqueous dispersion of hydrophobic particles, and thus a super absorbent polymer having an improved absorption rate can be prepared without deterioration in absorption properties.

Provided are superabsorbent materials composed of one or more water-soluble polysaccharides, such as gelling polysaccharides and gelling-compatible polysaccharides, and one or more insoluble fibers. The disclosed superabsorbent materials have a porous network structure and highly stable gelling properties as well as high absorption ratio and volume expansion capacity upon hydration or rehydration. Also provided are methods for preparing such superabsorbent materials and uses thereof.

Superabsorbent particles having less than 1000 ppm non-solvent, a median size of from about 50 to about 2,000 micrometers, and containing nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers are provided. The superabsorbent particles exhibit a Vortex Time of about 80 seconds or less.

Provided is a method for preparing a superabsorbent polymer. More particularly, provided is a method for preparing a superabsorbent polymer exhibiting remarkably reduced water-soluble components and generation of fine particles and exhibiting excellent absorption properties.

A method for concentrating rubber emulsion and a product prepared by the method are provided, the method includes: a concentrated latex is obtained by separating a superabsorbent resin added in advance into a rubber emulsion with a solid content of 0.01-70% after stirring and concentrating the resin-added rubber emulsion. The method requires simple equipment and consumes less energy, and the prepared polymer emulsion has a solid content up to 76%; the superabsorbent resin adopted herein is reusable after drying, which therefore effectively reduces the production cost; natural latex concentrated by the method has rather high yields of dry rubber and little wastewater production; products prepared from the concentrated natural latex have excellent mechanical property, aging resistance and adhesive property; and concentrating natural latex according to this method does not require advance agglomeration, which reduces the production procedures and improves the production efficiency significantly.

The present invention relates to a method for preparing superabsorbent polymer that introduces a plate type and rod-shaped clay additive in the superabsorbent polymer, and thus exhibits basic properties of a superabsorbent polymer equivalent to or much better than the existing superabsorbent polymer through multi-crosslinking, and particularly, can improve absorbency under pressure (AUP), and a superabsorbent polymer obtained thereby.
